How to Unlock the Ultimate Power Achievement for G.I. Joe: Operation Blackout

How to Unlock the Ultimate Power Achievement

To earn this trophy you must perform the ultimates of all 12 characters (6 G.I.Joes and 6 Cobras) in the game. This achievement can be done while in campaign or in local multiplayer. In order to perform a characters ultimate you must wait a period of time until the symbol in the middle of the bottom part of the screen indicates it has been fulfilled. You then just need to press LB + RB to start that characters ultimate. Once you have done this for all 12 characters the Ultimate Power Achievement will become unlocked.
