Halfbrick has just updated Jetpack Joyride with a giant high-fiving robot that you can unlock once a day. I don't even know where to begin.
Grab three flying tokens and you'll get to play as S.A.M., a giant mech who rampages through the levels, grabbing coins and generally making a mess of things.
Unlock him five days in a row and you'll be given a new costume piece for game protagonist Barry. You can also unlock the Sleigh of Awesome, though this only lasts through the festive period. Oh, and once it's gone, it's gone for good.
The S.A.M. update is live on the App Store now and should be available on Google Play next week.
