Jetpack Joyride is great and all, but I've always felt it was lacking one important element: the ability to play as an enormous homicidal robot.

Thankfully, the folks at Halfbrick have seen fit to correct this terrible oversight in the game's most recent update, codenamed 'S.A.M.' 

If you can get Barry to collect three tokens, then the stubble-faced aeronaut will leap into the belly of the giant mech. Check it out:

What's more, if you manage to hop inside S.A.M.'s metal chassis on five consecutive days, you'll unlock some bonus costumes for Barry. 

And, for those of you who already have Christmas on the brain (for shame) you can now purchase Santa's rocket-equipped sleigh, and lay siege to your laboratory while sleigh bells jingle.

Jetpack Joyride owners can download the S.A.M. update for free right now.
