Mass Effect Classes Revealed, Part Two

IGN has revealed three more character classes available to players in BioWare’s Mass Effect. The Sentinel:

Sentinels combine biotic and tech abilities. Typically they use biotic abilities and advanced healing skills to defend allies, though they can also disrupt opponents with biotic or Tech attacks. They are more efficient at tech and biotics than other classes, but at the expense of combat. Sentinels can only use light armor, and receive no advanced weapon training.
