What is now third-person multiplayer mode in Mass Effect 3 was almost a competitive first-person shooter called Mass Effect Team Assault.
“The goal was simple,” journalist Geoff Keighley reports in The behind-the-scenes iPad app, Final Hours of Mass Effect 3, “to create a standalone multiplayer experience in the Mass Effect universe that would mix the play styles of Unreal Tournament and Battlefield 1943 — and likely be released as a downloadable game.”
In development for four months, Mass Effect Team Assault was presented in March 2010, as the prototype seen in the screenshots above and below. Kotaku reports the main game’s engine wouldn’t allow gamers to play co-op in the main campaign of Mass Effect 3, but it would allow them to team up in a separate skirmish mode. Alas, Mass Effect Team Assault “was put on the back burner.”
