Sonic the Hedgehog 2 is one of the greatest platformers of all-time, and can be yours for $3 on Android and iOS devices. This version has been revamped by Christian Whitehead, who also handled the mobile revamping of Sonic 1 and Sonic CD. Sonic 2 hits with the same kind of visual overhaul, but with something brand-new – the lost Hidden Palace Zone from the beta that was never finished is now fully playable and has its own boss battle. Sonic, Tails, and Knuckles are playable as well, and if you’d like to control the game with a controller, you can – they’re supported natively. At a mere $3, this is a great buy given that it’s the most complete version of the game ever released to the public. OUYA owners will be glad to know that this game, like Sonic 1, Sonic CD, and both episodes of Sonic 4 works just fine when sideloaded.
