MASS EFFECT 3 Achievements Do Not Require Kinect
In addition to not a single Achievement dedicated to using Microsoft’s peripheral, leaked Mass Effect 3 Achievements show that players will be able to reach a hardy 1000 Gamerscore without ever taking the game online.
While some of the Achievements are now standard for the series, like “Renegade” and “Paramour,” most of the Achievements reward actions over story progression.
The multiplayer achievements are mostly standard fare and add up to just shy of 200 more points.
