Gears of War has always been a team oriented game. You rely on your teammates to support you in your mutual goal to decimate your opponents by any means necessary. The addition of Wingman made that even more of a challenge, since it was just you and your brother-in-arms to fight off other teams of two. Now Judgment is shaking it up again.
New info on this game mode will hit over the next few weeks, and I imagine we will get a few new tidbits at PAX Prime (Aug 31st-Sep 2nd).
