In this Comic-Con 2014 video, called "Charting a Course: Developing the Next Mass Effect," BioWare discusses what's what so far in Mass Effect 4 ("It's not Mass Effect 4").
First up is male and female armor, which are virtually indistinguishable from one another. I'm being ridiculous, but I'm disappointed that the look and feel strays further and further from the original Mass Effect's '70s and '80s retro-futurism.
Also, the terrestrial exploration vehicle—the Mako—is back from the first Mass Effect. I'm glad. It's removal was one of many cases where BioWare bowed to the complaints of a vocal minority.
Long video. But BioWare's marketing machine is going full throttle on Dragon Age: Inquisition at the moment. And while I'm 100% excited for Inquisition, hopefully they'll open up the flood gates on info for the next Mass Effect once Inquisition has enjoyed its limelight.
