If you're looking to party like it's 1993, you can now do it on your Android or iOS hand-held device, thanks to a new Sonic the Hedgehog 2 reissue from Sega. On top of the 11 levels and seven special zones from the classic game, the portable version includes the Palace Zone, a rarely seen beta stage that was cut from the original game. There's also a widescreen mode for easier portable gameplay, a "boss attack mode" and the ability to play as Knuckles along with Sonic and Tails. It's now on Google Play at $2.99 (like the original version) and should hit iOS later today. So, if you'd like to revisit your childhood, but at 60 fps this time, hit the source.
