Mass Effect Team Assault is a cancelled multiplayer FPS set in the Mass Effect universe, that was in development in 2010 by BioWare’s Montreal studio. The project was meant to be a downloadable game to be released on Xbox Live Arcade and PSN, with a gameplay that would have been similar to a mix between Unreal Tournament and Battlefield 1943. After 4 months of prototype development, the idea was canned and somehow evolved into a possible coop mode for Mass Effect 3 and later into the third-person multiplayer mode available with the released game. Info and videos from Mass Effect Team Assault were shared from “The Final Hours of Mass Effect 3” iPad app.
