Doeasnt need to be co-op. Like copkoir said he needs the 10K kills achivement so we need 10 people to set up a boosting match. PM me and I'll set it up.Sounds like a brill idea, but im not sure it'll be all that popular. Theres not that many games which have co-op.
Hope it works out though.
i was kinda joking about this im not to bothered about the achievement to be honest if i wanted to get it that badly i would of had it by now so it will come when it comes as it will take agesi need the seriously acchievment on gears im good enough to get it but i just dont have the time i reckon i have around 6k kills so i need around another 4,500 kills when you free for target practice
