15 Amazing Boss Fights In The Mass Effect Series

Reaper (Priority Rannoch) – Mass Effect 3

Starting from the revelation that the entire base is a Reaper, Priority Rannoch’s boss fight starts as a frantic escape and turret sequence. Orbital bombardment from the Normandy has no effect (at first) and Shepard is subsequently left to target the Reaper with airstrikes to bring it down. The actual battle involves dodging left or right to avoid the Reaper’s beam but the precise aiming needed for the targeting laser makes this battle challenging.
