If you’re wondering what that update for Mass Effect 3 was, BioWare has announced on its social network that it rolled out a minor patch.
Basically, the patch had two fixes: it fixed a multiplayer issue where users could have all of their weapons use rocket ammunition, and it fixed an issue with high memory usage when initializing DLCs.
DLC is believed to be on the way for the game - stay tuned for more info on that.
