15 Amazing Boss Fights In The Mass Effect Series

Thresher Maw – Mass Effect 2

Thresher Maws aren’t typically enemies to fight on foot but that’s exactly what Shepard and crew will be doing in Grunt’s loyalty mission. It’s far enough to avoid being smashed to bit but avoiding its acid spit is important, especially since it melts all but two pillars on the platform. Hiding behind those, taking down its armour (Warp is highly effective for this) and surviving are of paramount importance.
