BioWare notes "Secret Feature X" for Mass Effect 3
BioWare's teasing some sort of gameplay feature for Mass Effect 3 called "Secret Feature X." Staffers Billy Buskell and Preston Watamaniuk made note on the feature during separate tweets. It's not multiplayer, according to ME3News, though. Other than that, guess away.
Game's out on March 6 for PS3, 360 and PC. Thanks, Gamefront.
