Mass Effect 3 provides players with skills (or abilities) called "Powers".
There are four classes in Mass Effect 3: Adept, Engineer, Infiltrator, Sentinel, Soldier, and Vanguard.
Every player class will have access to First Aid, which allows the character to use medication to revive fallen squadmates, as well as restore some of Shepard's health.
Fitness is also available to all classes, providing increases to health, shield and melee damage.
Below is a list of powers available to each class.
Some powers are available from the beginning, and are marked with a YES. Powers that need to be unlocked via levelling up are marked with a Unlocked. No mark means that power is not available in that class.
