After lift-off, simply touch the screen to ascend and release to descend, raining bullets, bubbles, rainbows and lasers downwards as you fly towards higher and higher scores!
You'll start off with the legendary Machine Gun Jetpack to scatter the evil scientists of Legitimate Research, but throughout each game you'll collect coins and complete missions to earn cash and buy new gear in The Stash! Pick your favorite jetpack, snazzy outfit and stock up on items then get back out there!
Get a boost of speed and power using the Lil' Stomper, Profit Bird and Crazy Freaking Teleporter, just a selection of the vehicles pickups available - all playable with one touch controls.
Stay alive, get funky and lose yourself in Jetpack Joyride. There's so much to see and do, all the time in the world and more than enough jetpacks! As always, Barry Steakfries will provide!
