I'm looking for someone to team up with to finish Gears or War 2 doing it Co-Op and on INSANE difficulty. I haven't completed it on INSANE yet, so if you're upto the challenge and looking for the extra achievements, gimme a shout.
Remember that when playing co-op in Gears 2 you don't have to be on the same difficulty. The co-op partner can be on Casual, while you play on Insane. They can take care of all the hard work and you'll still get the Insane achievement.
