Third-person shooter-RPG where you command Shepard through a galaxy-wide war against the Reapers, mechanical beings systematically wiping out civilizations. You assemble a squad from multiple alien species—some returning allies, some new faces like soldier James Vega and AI-turned-physical EDI—then deploy them in cover-based combat missions. Battles use a class system with biotic (telekinetic) and tech abilities that chain into combo attacks when teammates coordinate. Blind-fire and stronger melee options expand your tactical choices. Story hinges on building alliances across star systems, though squad members can die permanently depending on your calls. Four-player co-op mode runs separate liberation missions; performance there affects your campaign's overall war effort score. Closing chapter of Shepard's trilogy, so prior games provide context but aren't mandatory.
