I honestly don't get all the hate for this one. Then I never gave a stuff about online multiplayer so if it sucks in that department I wouldn't know.
Just getting another 5-6 campaign hours of that delicious crunchy combat was enough for me. Very few other games make shooting baddies feel as satisfying as it does in Gears. I even liked the wave-based sections as it was essentially single player horde mode, and sign me the fuck up for that.
