Sonic's Ultimate Genesis Collection

Sonic's Ultimate Genesis Collection Achievements

Master the System

Unlock Everything  
Unlocking achievements will unlock most everything. To see what you need to do to Unlock everything, press Y at the main menu, and go over anything with a Lock icon on it, and it will tell you how to unlock it on the left side.

The only notable one is to beat the first boss of Sonic 2 with two players, cause it's not an achievement. Just start the game with two controllers, and press A on controller 2 during the boss battle once, and then kill the boss. It will unlock the only interview not linked to an achievement.

On Main Menu press Y it will take you to your extras, youll see a list of games on master system etc, to the left of the games youll see white triangles to the ones you already unlocked, the White locks will show if you havent completed it, scroll over the game with the lock on it and read what it says to do to unlock it.

If you did most of the other achievements they should all be open accept for 1 that is the sonic the hedgehog 2 game. for that one plug in a second controller to your xbox 360 and just play as sonic until you get to Dr robotniks first boss battle at this battle hit A on the second controller for tails - you can do it just once and fight the rest of the way with sonic - once the battles over achievement accomplished

I hate these stupid requirements that make you need more than one controller.

note. if your too lazy to get up and go across the room for your second controller your guitar hero controller works just fine.
