It's been a while since we got any sort of news on the next Mass Effect game. We've gotten hints over the years and yesterday was another. The teaser is pretty short with a female character mostly in black with an N7 logo walking, pulling out a gun, and continuing on her way. Not much else, but that's what a teaser is.
The last Mass Effect game was released around six years ago with Mass Effect Andromeda being a very lackluster entry into the series. Let's hope that BioWare can get back on track with Mass Effect 4.
