Looks like that Gears of War 2 patch didn’t fix this nasty little bug. As the hilarious video shows, the game’s walls, at least in multiplayer mode, might as well not even be there. Damage goes right through them. Utter chaos.
In fact, Kotaku calls the glitches “game-breaking,” but from what I’ve read, mulitplayer has been janky since launch, so this is just a cherry on top of the cake of failure.
Epic has yet to comment on these glitches, but I imagine it would be something like, “we’re aware of a minor issue affecting a small number of users that in on way hinders…” yada yada yada.
