Project Gotham Racing 4

Go to any track you want (but it has to be night out) and you have to have the lightning on. When you choose your car choose the grand Floridan just like the one in Back to the Future. You start the race and you have to go up to 88 mph or more when the lightning strikes. You then get an Achievement with a ton of letters and numbers.

Set up a custom race. Set the weather to "Storm" then race any opponents or the AI in a Delorean. When you reach 88 mph you will get the achievement.

Setup a custom race on the New York Outskirts route. Set the AI to 0. Choose the Delorean and begin. Make sure you are going 88 mph or faster when the lightning strikes to get the achievement.

Buy the gamer picture. As soon as you hear the achievement unlocked sound, turn off the Xbox 360. You will have unlocked the achievement, but get to keep the one million Kudos.

Go to Arcade mode. Select Chapter 1, and the first race. Do it under the Platinum difficulty setting. While racing, scroll through the songs until you get to Bloc Party - The Prayer. Leave it on and finish the race in second place.

Do a custom match in Las Vegas on the "Long Strip Straits". When the race begins, do a 180 degree turn and start driving the wrong way. On the left just down the road will be a casino named "Casino Royale". Stop here to get the achievement.
