Mass Effect 3 is due for a new patch this week (likely Thursday) that'll fix a metric ton of imbalanced and buggy BS.
The issues addressed by this latest patch range from tutorial pop-ups not displaying properly to certain powers causing entire matches to be rendered unplayable.
BioWare promised in a blog post that the update "will improve your gaming experience!" Xbox 360 and PS3 players will be prompted to install it automatically, while PC players will have to do it manually through Origin.
