Forum:XBOX 360: Need help with Circle of Duty

I need help with Circle of Duty: Corporal through the end. these are basically the last missions I need to get the completionist achievement. I have already killed Crawmerax I just need this. My Gamertag is also my name on here...

GT: Mindslave360 just message me hopefully today and ill invite you to my game. I would prefer you have really good weapons( I dont have any good stuff) or you be level 61...

OR is there some easy way I can solo this?
