Super Monkey Ball: Banana Blitz HD is gaining an extra character, but this one is a hedgehog, rather than a monkey.
Sega has announced Sonic will be an unlockable hidden character in the game – he’ll obviously be super speedy, and playing him will change all bananas in a stage to golden rings (with the classic sound effect to go along with them, of course).
There are other secrets to unlock in Banana Blitz HD too – there’s a whole bunch of costumes for each monkey, and some of these will even be Halloween themed.
