As cheesy as the title is. That is exactly what am asking. Are any competent Firefight players willing to get this achievement with me? I'm guessing it will be a lot of fun and will be a pretty cool experience. 
 
I was thinking we could get it sometime tomorrow afternoon. I live in Texas so that might be a little different for others wanting to go for it. My gamertag is Optimus Pohl. Just hit me up with a friend request and message saying you want to go for the Endure achievement. 
 
Also, does anyone have any advice what map is the best? I'm open to suggestions.
 

Alpha Site is by far the easiest and makes this achievement a joke with a relatively competent team. You could easily hold that map indefinitely as long as you didn't get bored.

I would but cross atlantic halo 3 co op equals mega lag. HEY MAYBES THE SQUAD BATTLE SOMETIME. ;) Although i haven't played it in ages
