I finally got around doing the campaign on insane and today i finally reached the last level with my friend. We breezed through it pretty easy. But the boss fight with the Queen is just torture. Its unreal how hard it is even with the mutators (infinite ammo and super reload) to beat her. The dam guards dont stop coming and the shriekers are just as annoying. Plus we have her flying around burning us. Not only have we died but we've also lost because shes broken through the generator and killed Adam Fenix. We later played with three and then four people and couldn't beat it. We finally gave up. Has anyone beat it on co-op!? Any suggestions!?
