Breakfast Time: To force the opponent to stop, you will have to spin them around. When your right behind them, drive up to the either side of the back of their car and give the car a little push to make it spin around at least 180 degrees. This makes the driver "confused" and will make him stop. All you have to do now is just stand right next to him for 5 seconds. Be careful NOT to damage the cars too much, this will fail the mission.

The Cadet: You must follow the waypoints throughout the track to reach the goal. Keep in mind that you can simply drive through every blue waypoint, but you'll have to wait or stop within a red waypoint. The start of this mission is quite annoying. You will have 2:10 minutes to finish the mission, no matter if you skip the conversation in the beginning or not. If you skip the conversation, you will start directly after the conversation is skipped, meaning you'll start a bit too early, and you'll have troubles reaching the goal in time. In other words, do not skip the conversation unless you want an impossible challenge.

To the Service Area: This is a race against two other drivers. You must finish first to complete the mission.

A New Case: Another waypoint race. Just try to follow the big arrow and use the radar to your advantage.

A Lot of Questions: Your objective is to jump each of the ramps without damaging your car too much. This is actually a track, and you will have to finish two laps. Look at your speedometer for a green arrow, this indicated the optimal speed you must have when jumping on the ramps to make a perfect jump. While part of the track is on the road, you have no time limit, so take your time and make sure you do not crash into the traffic.

Taking the Initiative: This is a shadowing mission, meaning you will have to follow a car, but stay within a certain distance. You are not allowed to get closer than 50 meters, and you are not allowed to get farther away than 130 meters. If you get too close or too far away, you have 6 seconds to correct your distance, which should be more than enough to brake or catch up with him. It seems that his top speed is 160km/h, so he's not slow, but you are still much faster.

Suspicious Behavior: You are now in pursuit of a taxi that you must force to stop within 3:40 minutes. Unlike in Breakfast Time, spinning him around is not enough. You must completely wreck his car. In order to do this, you will have to crash into him several times, until his damage reaches 100%.

Gunfight: You must race through a track marked white on the radar. You will get arrow indications of which turns you need to make. The percentage on the radar tells you how far through the track you have gone. Keep in mind that you will have to make a full stop in the red-lit area at the end of the track. If you're low on time and you overshoot it, you're done.

Stop the Suspect: This is another spin-the-opponent-mission. JUst drive up to him, spin him around, and stop by his side.

Motive?: Once again a race. Follow the highlighted path on your radar and make a full stop at the end.

Lab Work: I actually have no idea where you are supposed to drive here, so I made a video of the route I eventually found.


On the Cola Route: Another waypoint race, although this time the waypoints are all red waypoints, so you must stop in each one of them before continuing to the next.

Plan B: Gotta love the cool effects and the spot on "dammit" Schwarzenegger impression in this mission's briefing! Anyway, this is yet another waypoint race. Just follow the waypoints without taking too much damage.

Negotiations: You will have to shadow the car in front of you, this time he'll be a little faster than the last time. The distance window is minimum 50 meters and maximum 180 meters, with an 8 second distance correction window. The start of this mission seems to depend alot on luck, whether his route is clear or not. Sometimes he'll get away quite easily, while other times you catch up with him with ease. Nevertheless, you must be able to ace the first curves to actually keep up with him. Luckily the chase doesn't last that long.

Search: The culprits have crossed the river with a ferry and is now driving around on the other side, and you need to locate them and bump into their car 6 times. While this doesn't seem that hard, you have no indiciation of their location except from the red arrow on the radar, and you will pretty much have to guess the route to get to them. The messages you receive doesn't help much either ("heading away from the stadium"? Where the hell IS the stadium?). I've made a video of how I got to them.

Traffic Control: Simply follow the truck in front of you, which isn't hard at all. The distance window is maximum 200 meters, and minimum 30 meters, with a correction window of 3 seconds. Just stay on his back, eventually he'll crash into a traffic jam.

What's the reason?: Waypoint race. Follow the waypoint indications, drive through the blue waypoints and make a full stop in the red at the end. There are no damage limit, but there is a time limit. Though the route isn't that challenging, and you should have no problems getting through it after finding out where to go.

The Facts: Another waypoint race! But this time, you're driving a truck. Handling it is a bit challenging from time to time, but the mission itself is pretty easy.

Discrepancies: Woho, nitro! Use your nitro by pressing B (if you wish to), but make sure you hit all four ramps on your way to the precinct. Keep an eye on your speedometer for the speed indicator. This is also the first mission where you can get Nitro Burner. Simply hold both Left Trigger and Right Trigger down and then hold B until the nitro bar is emptied.

A Puzzle: This is a 6 minute red waypoint race, meaning you will have to make a stop within each one of them. The arrow will make a decent indication of which roads you must follow in order to reach the waypoints.

Last Try: You must follow the truck and drive alongside it (indicated by a box next to the cab) for 5 seconds. Then all you need to do is cross the finish line while driving the truck. Just make sure you don't damage your car too much (10% damage limit) and the truck (5% damage limit).

The Truth: All you will have to do is follow the truck. The distance window is 400 meters max, and 150 meters minimum, with a correction window of 4 seconds. Not that hard, in other words, just make sure you don't miss any of the truck's turns. The route is really short, but the 5% damage limit kinda makes up for it.

On the Run: This is slightly annoying. The objective is to make the escaping police car stop, and first you will have to bump into it 8 times, then you must damage it 100%. There is not time limit, but there is a hidden distance limit, meaning if you haven't been able to make it stop within that limit, you will fail. The optimal run here is to finish up the bumps inside the tunnel, so that you can concentrate on damaging him. Keep in mind that he will not take much damage while the bumping part of the mission is in effect, but when you've completed that he will suffer alot more damage in crashes.

Accident on the B1: Time limit race. Follow the path highlighted on your radar and finish it within 1:30 minutes.

The Witnesses: This is relatively hard. You must find 13 waypoints on your own, and there's no help except from the big arrow pointing the way to the next waypoint. To beat this mission, you cannot stay on the road, you must improvise some. You can see my route in the video.


Sports Car Sighted: Waypoint race with 4 blue waypoints, 1:30 time limit. After the first waypoint, you must make your way off the highway to the right. A little luck might be required to get this mission right.

Needle in a Haystack: Waypoint race within the parking house. You are supposed to navigate through the parking house through 13 waypoints without taking more than 15% damage within 2:30 minutes. The route is basically a zig-zag, so make a sharp turn whenever you drive through a waypoint to make the race as optimal as possible. When you reach the 11th waypoint, you must go down again through a spiraling road. This is probably where you'll take the most damage.

Short Cut: Ah, up the parking house again. Yet another waypoint race, but this time there are no waypoints. You will have to drive all the way up to the top of the parking house, then jump off the ramp to another building down below, then jump onto the highway. If you have problems making the ramp jump with the optimal speed, you now have nitro at your disposal.

Emergency: You are supposed to catch up with another car and stopping it without damaging it too much. There is a highlighted route need to follow, so taking shorcuts or cutting the turns too much are out of the question, but you can still do small shortcuts to get ahead. You should most likely not have much problems catching up with the car, and when you do, overturn it, drive in front of it and then hold down Left Trigger to brake for 5 seconds. Nevermind the yellow sports car, there's nothing you can do with it.

Plenty of Questions: This is a race against time. You have 1:00 minute to reach your destination (in which you have to make a full stop), but it isn't that hard. You have a faster car and you have nitro. You can unlock both Faster and Fastest during this race, if you can avoid crashing, that is. ;-)

Busted Interview: You are following the journalist. The distance window is minimum 50 meters and maximum 120 meters. Correction window is 6 seconds if you're too close and 8 seconds if you're too far away, and with the beast of a car you're now driving, that shouldn't be too much of a problem. His destination never changes, but his routes seem random (although they might be hardcoded). Keep that in mind, instead of expecting him to drive where he drove the last attempt at followed him.

Caught in the Act: The objective here is to damage the other car 100% to make it stop. Now, since you're driving two sports cars, this will be an extremely speedy race, and you'll most likely be trailing unless you drive really well. I found a trick to damage him 100% before the ramp jump over the Rhine: If you manage to get into the sewage tunnel, simply camp right in front of the ramp. He will brake because you're standing in front of him, and you are free to damage him. He will reset himself, though, but just repeat the process until he's wrecked. Flyover! will unlock in this mission, as it involves jumping from one sewage tunnel to another, across the Rhine. You can do Clear the drains! in the same portion of the race.

Stunt School: This is a stunt level. It's a circuit on an airport with 4 jump ramps. You need to score 20 jump points and finish first in the race of 4 laps. Scoring jump points: You'll get 1 point for jumping off a ramp, and a bonus point for landing on the opposite ramp. Once you reach 20 jump points, the instructor will notify you that you have completed the jumps, and you can focus on winning the race. Turn off brake assistant if you have problems building up speed for the ramps, and use nitro. If you have any left over nitro, which you should, at the long airplane track, use up all of it, as it will re-fill automatically once you cross the finish line.

Double Dealing: This mission seems to be based on luck, rather than skill. What you're supposed to do is bump into the police car 6 times, but you have to bump it very carefully, otherwise it will spin out of control. This is very hard to accomplish. If you fuck up too much, you have already lost the next part of the mission: When you have successfully bumped into the police car, you are supposed to follow the car the police car was tailing, and the max distance you can stay behind is 250 meters. If you have messed up too much with the police car, it is very probably that he will be >1000 meters in front of you. If he's in range, you just have to follow him to a gas station.

Trial Run: This is a two lap race between you another driver. Try to drive as fast as you can in the beginning, because if you're lucky, you might be able to have the other guy stuck behind a train. This will give you a serious advantage (beyond 1000 meters, depending on your driving skill). The only problem is that there's alot of obstacles throughout the race, and you can only take 20% damage. You also have nitro at your disposal.

Undercover: A follow mission. You can stay a maximum of 80 meters behind the vehicle you're following, and you only have 4 seconds to correct the distance. The car you are following does not really go that fast, and you have no minimum distance, so you can stay up in his ass if you so wish. Although, I would recommend that you keep a safe distance, as his routes are pretty random. If he makes a sudden turn and you haven't got the chance to react, you might have lost it already.

The Tuner Scene: This is a two lap race where you must drive through a narrow and trafficed track, and the 20% damage limit is a pain. If you have problems with the track, use brake assistance.

Happy Hours: This is a four lap race against several opponents. The objective here isn't to win, but to not lose. It's bascially a knock out race, meaning that the last car to finish a lap is out. In the final lap, there will be 3 cars racing, so as long as you do not finish last, you will pass the mission. Sounds easy, but it's quite challenging. 20% damage limit, of course.

Test of Courage: This is a waypoint race with 16 waypoints and 5 ramps, which you will have to net 9 jump points from. This means there are only 4 ramps with an opposite landing ramp, while the last is on the ferry Jenny. If you are having problems getting the 9 jump points, you can actually do the Jenny jump 3-4 times. Simply jump of the ramp, wait for the ramp counter to add one jump, then press select to reset your car, then repeat the jump.

Change of Shift: You are following a car with 4 bad guys in it. They are driving around town boosting cars, and you must keep up with the "leader car" (the one with the huge arrow over it). The stolen cars are nothing but nuisance, but they have no other purpose than that, I believe.

The Leader: Another follow mission. You are going to go through the sewage tunnels this time. Make sure you do not stay too close to him, because he makes a few sudden turns. If you have no chance to react to them, you are screwed. Once you exit the sewage tunnels, you are done.

A Breakdown: This is a waypoint race that will take you to the other side of the highway, then back onto it. There are only two waypoints here, a blue, and a red you must make a full stop in. If you have problems getting through in time, you can take a shortcut to the blue waypoint. From the starting point, do not drive out onto the highway, instead, turning right as if you're going onto the highway, keep to the right side of the guard rail, avoding the trees, then drop down into the tunnel below the highway. Drive through it, and voila, you're on the other side!

Important Meeting: This is a waypoint race with 6 waypoints, and the time limit here is 3 minutes. This is a pretty rough track, and you will have to be relatively fast. You are supposed to go to a building site. If you crash through one of the barracks near the red-lit waypoint, you will unlock Builder.

Welcome: This is a car chase mission. You are supposed to first bump into your opponent 6 times, then force him to stop (spin him around), but without damaging your car or his car too much (both cars have a 10% damage limit). Sounds hard? Well, it isn't! You start off at the site where you ended the previous mission, and there's alot of open terrain here and no cars. Although, if you are unsuccessful in bringing him to a stop quickly enough, the chase will be taken out to the road. The optimal thing here is finishing him off before he reaches traffic. Just make sure you do not crash into him, but slightly touch him, and you should be fine.

Next Exercise: The objective here is driving through 22 waypoints (stopping at the last red one, of course), and racking up 12 jump points in the process. Oddly enough, some of the ramps doesn't give a single point, but this can easily be corrected by reseting your vehicle on another ramp that gives points. For example, after the first waypoint, simply jump of the ramp leading the next waypoint, then instantly hitting the back button to reset, then jump over it again. Or you could do it where you have to jump two ramps to reach two waypoints (I usually reset my car here once I've hit the top waypoint to avoid getting damaged here). Anyway, this course has to be completed within 3:50 minutes, and with no more than 25% damage.

A Matter of Feeling: This is a little fun! You are supposed to drive around the track locating 4 cars and, in order, blow them up with an RC unit! Just follow the waypoints with your car, and when you're close, release the RC unit by pressing down the Right Stick, drive under it, press Right Stick again, and BOOM! Har har, too much fun. The time limit here is 1:40 minutes.

The Search: You are going to leave the site now ;~(. You have 9 waypoints to get to, within a time limit of 3:00 minutes. Remember, this car is ridiculously strong, and can climb out of the site by going straight up, so don't bother following the road.

An Unpleasant Surprise: There are 12 red-lit waypoints around in the area, which you need to find the way to yourself within 3:10 minutes. Thankfully, unlike the mission The Witnesses in A Series of Accidents, this is pretty easy, as all of the waypoints are pretty close to each other. It only took me two tries to get a decent route.


Faster: Waypoint race. There are 6 waypoints on this track, and you have 2:00 minutes to reach them all. You are driving a beast of a sports car in trafficed area, and with the damage limit of 10%, it isn't exactly easy.

Damned Fast: Formula racing! Man, the title does not lie when it says damned fast, because you will be going at speeds up to 360km/t. That's over 220mph! I found this very hard to do without having brake assistance set to normal, but if you're a formula racing talent, you will probably do much better than me. There's no damage limit here, but trust me when I say that you should thank God that there isn't! The other drivers doesn't care whether you live or die, and if you do not respect the curve indicating arrows (that turns red when you drive too fast), you'll do tons of self damage.

For Sale: You're in a sports car following a van. The distance window is 30 meters minimum and 70 meters max, with a correction window of 6 seconds. This is pretty simple, probably the easiest mission in this case.

Over 300 HP: You are supposed to "escort" your opponent. By this, the game means that you have to drive up to either of his side and stay in that position for 3 seconds. This seems pretty hard at first, at these speeds, and it is unless you're able to finish him off quickly. After exiting the garage, there are two turns your opponent will make, where you can cut the turns by alot. If you are able to do this, you will be in front of him. Simply let go of your gas pedal for a little while (do not brake!) and just wait for him to gain some speed, then accelerate again. If you're lucky you should both be at about the same speed, and all you need to do is position yourself right next to him.

End of the Day: There are two stop waypoints that you must drop by here. The first one is at the gas station, and the other is at the friend's house. With 1:05 time limit, you are under some time pressure, but this track is shortcut friendly.

Attempted Murder: This is a follow mission. The distance window is 20 meters minimum and 80 meters maximum. Correction windows are 8 seconds if you're too far, and 6 sconds if you're too close. The route this guy takes is pretty awkward, but keep on his tail long enough, and you'll witness another care being blown to bits.

Second Incident: You have 2:10 to reach your destination. The easiest way I found to get there was to drive straight ahead over the meadow from the starting point and onto the highway. From there I took the first right and kept on following the road, and took a left in the T-intersection.

Don't Touch!: This is actually a race on a highlighted track, so it's not really that shortcut friendly. There's a bomb on your car, so you can drive no slower than 40km/h, and you have to reach your destination in 1:10 minutes. You can do a lot of shortcuts in the mountain-climbing road, if you cut the curves a little. At the end of the track, you must press your action button (Right Stick with the default controller layout) inside the blue highlighted area. I found that you must press it exactly when it says "Jump Off", or else you'll explode. My advice to you is to drive a little over 40km/h here to make it alot easier to time.

On the Scent: Waypoint race. There are 3 blue waypoints you must drive through. The time limit is 1:40 minutes. Stay sharp on the 3rd blue waypoint, because the next waypoint is to the right. You will need a sharp turn to get to it, so make sure you don't go too fast!

Emergeny Call: First you will have to locate the ambulance. From the military base, take a right and follow the road. Once you get in range (400 meters), the maximum allowed distance will become 400 meters, so make sure you dont mess up too much. At some point the ambulance will turn towards the digging site, and this is where you're supposed to escort the vehicle. Simply position yourself on either of it's side and hold it for 5 seconds.

Relief: Waypoint race with 5 blue waypoints and 1 red waypoint. The time limit is 2:50, which can prove to be too little time, unless you ignore the road in the beginning. Simply stay by the digging site's edge and follow it until you reach the first waypoint. If you time it perfectly, you can jump down to the road on which the waypoint is.

Conjecture: This is an off road mission, mostly. Your objective is to bump into the opponent 18 times, then follow him back to the army base. Easy enough? Well, you have a 10% damage limit, so you cannot crash into him. Be gentle, and you'll finish this mission in no time.

By Any Means Neccesary: Tank driving time. You are supposed to follow this guy around with a tank, and the maximum distance you can stay behind is 100 meters. Interestingly he's a crappy driver, and most of you time you should be right up in his butt. If you have problems with this mission, I'm seriously gonna start wonder how you made it this far. Great comment at the end, by the way. "He's a better driver". :-D

Cracking the Armor: This seems really hard at first. You're supposed to follow the tank driving on a highlighted track, and then blow it up with RC cars. It really isn't hard! Just catch up with him, and drive up behind him. Once you've positioned yourself directly behind him, launch an RC unit with clicking the Right Stick, then drive under his tank, and click the Right Stick again. BOOM! Repeat 5 more times.

The Speeder: Catch up with the guy, and force him to stop, meaning inflicting 100% damage. You have nitro, so this should be pretty easy.

By Chance: There are 13 waypoint stops you will have to make here, and the route are completely up to you. I'll attach my route so you can see how I did it.


The Wager: You are supposed to reach the stadium in this race. There are 2 waypoints (1 blue and 1 red) and 1:30 minutes time limit. You must take a right off the first highway, then on the other freeway, you must make another right to get off the freeway, and near the stadium.

New Evidence: Ok, you have 1:10 minute to navigate through town and onto the other side of the river. It took me ages trying to figure out a route, but I finally managed it. I don't know if it's the fastest, but it will get you there in no time!


Stay On It: Follow mission. Keep up with your opponent until he reaches a gas station. You have nitro, so it shouldn't be too hard. 30 meters minimum, 140 meters maximum, 6 seconds correction window if you're too close, and 7 seconds if you are too far.

Goodbye: This is a spin-him-around mission. Get up behind him, and spin him around, then stop by his side. Watch out for the damage limits, 15% for both you and him.

Dead End: You're supposed to find Hartmut. The easiest way to do this, is actually following the helicopter. Once you locate his vehicle, you must get in range, which is maximum 160 meters max. Hartmut will stop in the tunnel, but to change cars. Onto the next chase!

Desperately Missed: You must follow the chopper once again, but now your destination is the airport. After the first blue waypoint, you should get to the red stop waypoint on the landing strip as fast as you can, because once the chopper lands, there will be a distance window of maximum 30 meters.

The Warehouse: Another waypoint race. You need to get back to one of the warehouses you visited in the By Chance mission. There are 3 waypoints, and you'll have 1:20 minutes to finish it. You'll need to be pretty fast here.

Observation: This is a bit tricky. First you'll have to chase that sports car and inflict 100% damage on him. If you're good enough, you can damage him up to 50% or more if you crash into him before you reach the road. After you've damaged him enough, you'll have to get back to the warehouse (without any other indication than the usual meter on the left hand side telling you how far from a car you are). In other words, try to finish him off quickly so that your way back isn't that long. You will have 4 minutes to complete this mission.

The Chauffeur: I found this one hard. You must get to a location you have no idea where is, you have 2:40 minutes on the clock, and your damage limit is 5%. Here's a video of my route to the location, and I still barely make it, with only a few second left on the clock. There's got to be a better route, but if you can handle driving recklessly, you could follow mine. Quite the limo ride, I must say. :-p

Incident: Waypoint race with 4 waypoints within 1:45 minutes. The biggest problem here is the crossing trains that could screw up your time, especially the one right in front of waypoint 3. If you can't be the train here, you're screwed. The stop point is within a warehouse.

Rendezvous: Ok, first you need to clear 4 blue waypoints, then you need to jump off a ramp and onto a train. Even though there are no time limit, you need to move fast, or else the train is gone. Be very aware of your speed just as you approach the ramp, the ideal speed is a little over 40km/h.

No Escape: This is a bit tricky one. You have 2:00 minutes to clear some waypoints and reach the stadium, doing 3 ramp jumps in the process. You must have 5 jump points here. Then when you arrive at the stadium, you must stop within a red-lit waypoint and wait for 7 seconds. Then you have to head to the airport as fast as you can, and reach a car inside. Pretty challenging. Make sure you try to get perfect jumps on the ramps no matter what, especially the last one, because it doesn't seem to even give one jump point if it's not perfect. Use your nitro wisely!

Unauthorized Access: Ok, you will have to force this guy to stop, and you will have to stand beside him for 6 seconds to complete the mission. You both have 10% damage limit. I had problems having him stop by just spinning him around, so I actually rammed him off the road, then stood in front of him while holding Left Trigger and Right Trigger down, which forced him to stop completely, while the countdown went down to 0.

Dangerous Rescue: You'll need to catch up with this guy, and then "escort" his car for 3 seconds, meaning staying inside the blue boxes on either of his sides without going out of it. There is not time limit here, but there is a hidden distance limit, so you need to drive pretty flawlessly to get it right.

The Accomplice: You will have to force this opponent to stop by inflicting 100% damage on him within 3 minutes. From when you start on the highway, take the first right, then the first left in the T-intersection. If you're lucky, your opponent will come right at you and you can do ~20% damage on him. If you're both on the highway, with him having little damage, you might have problems catching up with him, and usually it's pointless to go on here. When you've done the 100% damage, you're done!

You are driving a really fast car with lots of nitro, and all you need to do is boost as much as you can to gain enough speed. Eventually you will reach 350 km/h. You can also get Faster quite easily here.

Drive in reverse gear for 100 meters at a minimum speed of 10 km/h without collisions

Guide
At the start of most missions, you will have a clear path behind you. Put the car in reverse, and go full speed until the achievement unlocks.

Stay in the lead by 100 meters for at least 5 seconds in a single race

Guide
This cannot be done in the cases, but in the single player races. Simply load up any race, and take the lead.

Use up a whole nitro charge in one burst without collisions

Guide
In the Discrepancies mission of the Traffic Control case (see 'Traffic Control' - Hard) you are given nitro for the first time. Simply hold down Left Trigger and Right Trigger and hold down B to launch nitro. You will be completely still on the ground, while the nitro is emptied.

Drive the 'Semir' until the car is covered in dirt

Guide
By 'Semir', they mean the Plain car in the Semir category (when you choose your vehicle going into a single player race). Combine this with Schuminator. It should unlock around the 7th lap.

Drive through a site hut

Guide
Your first chance to do this is in the Important Meeting mission in the Mere Chance case (see 'Mere Chance' - Hard). At the end of the race, the red stop waypoint is by some huts. Simply crash through one of them.

Lap your opponent and win a single race

Guide
Here's how I did this. I chose the race Around the Quarry, circuit, 15 laps, 5 opponents, brake assistance normal, and the Plain car in the Semir category. You will have to finish the race with the summary saying 1 Lap+ in order to unlock this achievement. Within 15 laps, you should have been able to lap each and everyone in the race. This track is extremely shortcut friendly, and you should have no problems in getting the achievement here. Chosing the Plain Semir car will also unlock Dirt Drive, so I would recommend that you go for this achievement with that car.

Spiral down a sewer tunnel

Guide
This can be done in the mission Caught in the Act in the case A Series of Accidents (see 'A Series of Accidents' - Hard, as the race involves going through a sewer tunnel.

Land a perfect jump from the sewers across the Rhine

Guide
This is done in the mission Caught in the Act in the case A Series of Accidents (see 'A Series of Accidents' - Hard). Just after you enter the sewer tunnels, there's a ramp, as part of the track, that will have you jump over the Rhine, landing on a ramp in a sewer tunnel on the opposite side.

Viewed the entire 'Credits'

Guide
Simply watch the Credits from the Main Menu.

Police light successfully tested!

Guide
This can be done in the first mission. Simply tap X until the police lights are turned on.

Knocked over 1,000 objects

Guide
This will come by time, depending on how you play. It should, however, unlock before you're able to finish the cases. If not, keep playing the game until it does.

Driven 1,000 kilometers in the whole game

Guide
This one will be unlocked once you start racing. If you are going for the full 1000 points, you are bound to play each of the racing tracks, and this will most likely unlock this achievement in the process, given that you've already completed all of the cases.
