Have a friend set a score on any event and send it back to you as a challenge. All you have to do is do better than them on that event and the achievement will unlock.

You will most likely get this without trying, but you can try to boost this by having a friend do poorly on a race they have not done yet and you can easily beat their score if you want the achievement fast.

At the Main Menu, select “Wall” and press  to create a post. This achievement will unlock when going for several other achievements as well, so it is pretty hard to miss this one.

During an event, you can pause the game and take snapshots of the track and cars. You may also take Dreamshots at the vehicle select screen. This will also unlock the "Share the Joy" achievement if the first Dreamshot you upload is of a BMW.

Just have 5 people on your friends list that have played Need for Speed Hot Pursuit or the Demo. The achievement unlocks as soon as the game sees your 5th friend in the game or if you have 5 friends, it unlocks after the Autolog sets up for the first time.

This will unlock the first time you bust a racer in any game mode.

This can be done online.

Reach the top rank as the Enforcer. You will need 2,000,000 bounty to get to rank 20. Online and Offline modes apply to this rank. Getting all Distinction Medals in the Career will help you rank up to about rank 12 or 14. You can replay events in the career to keep gaining bounty.

For Single Player, you can boost your Enforcer Rank using any of the Special Response Unit events you are good at doing. I found the event "Fight or Flight" good for gaining bounty fast.

Here is an online boosting method found by Turkdaballa6:

1. Start a private match with 1 other person.
2. Player 1 will start out as a cop and Player 2 as a Racer.
3. Player 2 will stop at the start of the race and Player 1 will stop next to them to bust them fast.
4. The next round, Player 1 will be a racer and turn around and drive the opposite way as Player 2 so they escape to end the match quickly.
5. Switch side and let Player 2 win as each side.
6. Repeat to level up.

You should get around 8,000 bounty per match.

There are 48 Enforcer Events to get Gold on. This will take about 10 hours and some retrying of events to place first. Try to stay behind a racer to slipstream and practice drifting to help build up your nitrous. Keep practicing and most of the events should not be too much of a problem except for some really tricky ones that should come if you just keep at it.

Some tips are:

• Learn when to boost. Going up hills and long straight aways will be perfect times to use your precious nitrous.
• Explore the shortcuts. Some shortcuts will help you a whole lot and others will mess you up even more. If you are having trouble with an event, find out which route benefits you the best.
• Drift. This is one of the better ways to get your nitrous refilled and will help you from hitting walls on those sharp turns.
• Do not waste power ups. These will help you during Interceptor events and Hot Pursuits. Start the events trying to use brute force to take out your opponents. When you are getting low on time or have a lot of racers about to be knocked out, use your equipment and take them out.

You can restart the event if you mess up to bad so you do not have to watch too many loading screens. On the downside, you do not get any bounty if you do this. So if you are getting 2nd or 3rd place, the bounty you earn can help you rank up for the rank achievements.

Reach the top rank as a Racer. You will need 2,000,000 bounty to get to rank 20. Online and Offline modes apply to this rank. Getting all Gold Medals in the Career will get you to rank 12 or 14 and take about 20 hours.

For single player, you can replay any Hyper Series events you are best at for the best bounty rewards. I found the event "Spirit of Performance" the best for grinding out bounty because it's short and easy.

Here is an online boosting method found by Turkdaballa6:

1. Start a private match with 1 other person.
2. Player 1 will start out as a cop and Player 2 as a Racer.
3. Player 2 will stop at the start of the race and Player 1 will stop next to them to bust them fast.

You should get around 8,000 bounty per match.

There are 60 Events in the Racer Career to get Gold on. This will take about 15 hours and some retrying of events to place first. There will be a few Time Trials that will give you some trouble, but if you keep practicing, you will persevere.

Some tips are:

• Learn when to boost. Going up hills and long straight aways will be perfect times to use your precious nitrous.
• Explore the shortcuts. Some shortcuts will help you a whole lot and others will mess you up even more. If you are having trouble with an event, find out which route benefits you the best.
• Drift. This is one of the better ways to get your nitrous refilled and will help you from hitting walls on those sharp turns.
• Do not waste power ups. These will help you during races and hot pursuits. Start the races trying to use brute forces to take out your opponents. When you are getting low on time or almost have a cop knocked out, use your equipment and take them out.

You can restart the event if you mess up too badly and think you are going to lose. On the downside, you do not get any bounty if you do this. So if you are getting 2nd or 3rd place, the bounty you do earn can help you rank up for the rank achievements.

When an Enforcer calls in a Road Block, keep an eye out for it and when you see it, drive around it and make sure you do not hit any of the cars in it. The Road Block must be previously undamaged, so it will work best if you are in first place or ahead of everyone else during the event.

A BMW unlocks early in the Racer Career. Just start any event with it and take a Dreamshot. After the event, go to your pictures at the main menu and upload the image of the BMW to your Wall for the achievement.

You will unlock this car early on while playing as the Enforcer and the Racer. After you have the car, start an event and drift on every turn. You can also pick an event on Builder Desert such as "Lightning Reflex" for the Enforcer and at the end, do a donut around the rocks in the big sandy area on the right side of a big turn.

To Drift, tap left and let go of  briefly and tap  while turning at a decent speed. You can then hold  when you start drifting and the direction you wish on the Left Stick to do a donut and keep drifting around one of the big rocks.

You do not however, need all 2000 drift points in one drift. It is fairly easy to get 2000 points before the end of the event without doing donuts or you can just turn around and build up some more points before finishing the event.

First, Unlock the Ford GT in the Racer career. The car is with the Exotic Series of events. Then select it when starting a race on any of the desert tracks that have a moon under the weather conditions and select Midnight Blue Metallic as the paint color. Then, just pause the game during the race and take a Dreamshot of the car.

There have been reported issues with this achievement not working correctly. To fix this, start any night time event in one of the desert areas and once the event starts, back out of it and start a free roam. Once in the free roam, you should start in the same area you last raced in. Pause the game and take the snapshot for the achievement.

There are 8 Racer events in the Super Sports Pack DLC. Once again, there are Time Trials that will slow down your progress. Just keep practicing and find out what shortcuts benefit you the best and do not crash.

Here are some tips for the Time Trials:

• Awe Inspired - At the start of the event, there will be a dirt road shortcut. This shortcut goes through about half of the event and will give you a little bit of extra time that will make your life easier.
• Pushing the Envelope - This is the event that will make you pull your hair out. Keep practicing and practice some more!
  -Some good tips are to only take the first 2 long short cuts. The first shortcut is at the start after the first cop and the other is on the left right after you pass the airport.
  -The next tip is pretty important. Only attack the cops if you really need to. Avoid them the best you can and use spike strips to take them out. Save your Jammer for the helicopter spikestrips if you can't dodge them fast enough as well. If you can, use up your boost before finishing off a cop because you get your boost refilled when you take them out.
• Fast Track - Start out on the wrong side of the road. You will get a ton of boost and it's pretty easy to dodge the traffic. I had a pretty big crash and still made it with 7 seconds to spare.
• Rocket Science - This one you will eventually pass with a second or two left on the clock. The trick to this time trial is to take the big loops with a perfect drift. Save your boost for the second loop because it's easy to hit a wall or mess up and you need to get out of that loop as fast as possible.

There are 5 Enforcer Events In the Super Sports Pack. These events are a little harder than the ones in the main game. Just keep practicing and test short cuts to see how well they work for you.

The Rapid Response event "Duty Calls" is the only real hard event for the Enforcer. You will need to take some shortcuts but not all of them. Some of the shortcuts are too complex to be of any help. If you hit more than one thing, I would suggest restarting the event. I hit 1 wall and got a 2 second penalty and made it with half a second to spare.

Do the first Enforcer DLC Event "Show of Force". You are forced to use the 911 GT2 RS and you start with 10 spike strips. Just hit any 5 cars with a spike strip and the achievement will unlock.

This has to be done in a single drift. You can do this in an event, in free roam, or online. I did this in free roam on the highway doing donuts around one of the overpass supports in East Gorge Canyon. Just slide into a drift and hold the gas and left or right on the  to keep sliding in a donut shape.

There are several events that force you to use the 911 GT2 RS in this DLC. During any of those events, take a photo of the car with  or pause the game and take a dreamshot. After the event, go to the main menu and look under photos. Post the image of the Porsche to your Wall to unlock the achievement.

Play any Hot Pursuit or Interceptor events that have the Apollo S available and bust the racer. This will be easier in Hot Pursuit mode because there are several racers and they are easier to catch than in Interceptor events.

This is an easy one. Just do any event that has the Bugatti Veyron 16.4 Super Sport available and get a good straight piece of road and hit the boost. When you get to top speed, hold it for a whole 2 seconds to unlock the achievement.

*Requires an Online Pass*

Play any single player Interceptor match that has the Bugatti Veyron 16.4 Super Sport Interceptor available and complete the event with any medal. Then, play an online Interceptor match with the Bugatti Veyron 16.4 Super Sport Interceptor and bust the racer in that event and the achievement will unlock.

In Gauntlet or Hot Pursuit modes, use the GUMPERT apollo s, and wreck 5 cops total. The DLC event "Hunted" is a good place to work on this achievement.

This can be done online.

*Requires an Online Pass*

Play online and do 5 races using the GUMPERT apollo s. You do not need to win for this achievement, just finish the race.

Just play any event that has the Bugatti Veyron 16.4 Super Sport available and beat a friends recommended time. If you are having trouble with this, have a friend post a poor time on their wall and let you beat their score.

*Requires an Online Pass*

Simply play an Arms Race match online and take down another racer.

*Requires an Online Pass*

Just play 5 games of Most Wanted as a Cop. You do not need to win. You can make the games go faster by having your friend stop in the road and you bust them as soon as the match starts.

*Requires an Online Pass*

Similar to Chase the Ace, but play 5 games of Most Wanted as a Racer. You do not need to win, just complete the matches. You can make this go faster by stopping in the middle of the road and let you friend bust you right away.

Just play any event such as "Resisting Arrest" in the Lamborghini Untamed DLC and choose the Lamborghini Countach and take 3 pictures with  or pause the game and take a dreamshot. This also works in the car showcase photo mode before you start an event or free roam.

Do the Racer event "Comeback Tour" in the Lamborghini Untamed DLC. Save your nitro for about half way through the race and you will be near a tunnel. Hit the boost and don't crash and you should unlock the achievement. It will work anywhere in this event or even Free Roam but I found this pretty easy to do and you still need gold in the event so there should not be any trouble unlocking this achievement.

Use the Lamborghini Sesto Elemento and save up your nitrous until you get to a large straight piece of road. When you get to a good spot, use your nitrous and hold it until you run out and do not hit anything to unlock the acheivement. The event "Foot to the Floor" from the Lamborgini Untamed DLC seems to be the best for this achievement because it's long and there are plenty of opportunities to use your full nitous bar.

There are 5 Racer and 5 Enforcer events in the Lamborghini Untamed DLC. There isn't much that you have not done before in the original game or the first DLC outside only racing against Lamborghinis most of the time. Make good use of your nitrous, weapons, and do not crash and you should not have any trouble with most of these events. They were the easiest of all the DLC events so far.

*Requires an Online Pass*

Just play online and make sure you use the Porsche 911 Turbo found in the Sport class. Once you win the event, the achievement will unlock. You can take turns winning in a private match with a friend to make it easier. You may also do this while playing the Armed and Dangerous DLC to knock out 2 birds with one stone.

This can be done on any event or online. The Racer event "Fast Lane" from the Porsche Unleashed DLC will get you started on the achievement as you will play through the event while trying to get a Gold Medal. The car isn't that great so if you find yourself doing poorly then just finish the race and do it again and you should have enough shortcut mileage for the achievement. 

You can also try it online and have your friend sit at the starting line and let you just drive around in shortcuts until the achievement pops and then finish the event. Then let your friend get the achievement.

Note: this achievement unlocks after you finish the event and leave the Screen that shows how much bounty you wont and your time.

The Racer event "Sunset Racers" from the Porsche Unleashed DLC and that will give you 19.5 miles towards your achievement but the achievement unlocked after I left the event so it may be just driving close to 20 miles. If not, just play another event with the 911 Speedster or Free Roam for a minute and the achievement will unlock.

Note: this achievement unlocks after you finish the event and leave the Screen that shows how much bounty you won and your time.

There are 5 Racer and 5 Enforcer events in the Porsche Unleashed DLC. There isn't much that you have not done before in the original game or the first DLC outside only racing against a Porsche most of the time.

There are no crazy tough events though some might take a couple of tries, especially with the older model cars that you are forced to use a few times. Make good use of your nitrous, weapons, and do not crash and you should not have any trouble.
