Ammo Powers in Mass Effect 2 allow players to use different kind of ammunition. In Mass Effect 2 you do not gather elemental ammunition, but you can use Ammo Powers to load your Weapons with special Ammo that can change the type of damage dealt to enemies. As you level up, you acquire Squad Points that you can spend to improve these aspects of your character. The Powers available to you and your squad are determined by the Class selected in Character Creation.
Power Levels
Except for Unity Power, all other powers can be leveled up to 4 ranks for a total cost of 10 squad points. Regardless of the upgradeable power, each level rank requires the same points as the rank:
- Power Rank 1: Requires 1 Squad Point
- Power Rank 2: Requires 2 Squad Points
- Power Rank 3: Requires 3 Squad Points
- Power Rank 4: Requires 4 Squad Points
Once a Power is upgraded to Rank 4, players need to choose between two final evolutions of that Power. Once you have chosen an evolution, you can not change it back.
