Bonus Ammo Powers are a category of Bonus Powers in Mass Effect 3. Bonus Powers are unlocked in-game and become available on the Character Creation menu once they are unlocked. Players may only select one Bonus Power.
You can earn one additional bonus power during your playthrough. Bonus Powers can be unlocked by talking to your Companions or by completing certain DLC missions. You can unlock two bonus powers per squad member. You have to have at least two playthroughs because you either have Ashley Williams and Kaidan Alenko alive, so you can't obtain both Powers in the same playthrough.
Bonus Powers belong to the same categories as the common Powers Commander Shepard can obtain during the game.
