BioWare has published a series of tweets teasing "the next chapter of Mass Effect".
Key Mass Effect staff, from series producer Michael Gamble to executive producer Casey Hudson and BioWare Montreal studio director Yanick Roy, took to the social network to post a number of images of staff at work on Mass Effect 4.
BioWare Montreal has taken over development duties on Mass Effect, with original developer BioWare Edmonton now working on a brand new IP. The story of Mass Effect 4 won't relate to Shepard or the events of the previous three games, while the new title will share "core systems" with Dragon Age 3.
