Jetpack Joyride

The "CFT" is the Crazy Freaking Teleporter vehicle in the game. This achievement is best obtained by equipping the "Free Ride" gadget which allows you to automatically start in a random vehicle every time. If you do not spawn in the CFT, move forward and die as fast as possible. Keep repeating until you start with a CFT, then try to reach the 800 meters. If you fail and run into an obstacle, immediately pause and restart. You will again be in the CFT, able to reattempt this achievement again. The key to using the CFT is to try to stay at either the top or bottom of the screen. As soon as you are about to smack into an obstacle, tap the screen to teleport to a new position. Most of the time this works flawlessly, but occasionally you will get unlucky and teleport directly into another obstacle and die. Once you get this technique down, this achievement should only take a couple tries.

You must travel over 800m continuously in the Crazy Freaking Teleporter (CFT). Though this may seem daunting, it is fairly easy once you get the hang of it. If you wait until you are about to strike a zapper and then teleport, you should be able to avoid any other obstacles 9/10 times. You can have bad luck and teleport directly into another zapper, though this typically only occurs at higher distances.

To farm this easily, purchase and equip the "Free Ride" gadget (under Sector 5: Testing Zone) in The Stash. You will start out with a vehicle at the beginning of the level and, if it is not the CFT, kill yourself and try again. If you fail prior to reaching the 800m mark, you can simply click the pause button, and retry and you will spawn with the CFT again.
