Me and my buddy are have been trying to get Endure, but we havent been able to get anyone to help us with it. So we tried a few times just having a guest on each of our 360s and just hiding them. It would have worked alright, but since they are just sitting there its just the two of us taking everybody on.
We just need 1 or 2 people to hop on and help us out. We hold down the central building as i stay up top and laser the wraiths that get dropped off, while he uses the hog as a turret tucked away in the bottom area. He also goes out and jacks every chopper he can and stores them under the stairs so once the wraiths are gone we can go clear off the battlefield with them.
Its a really solid strategy, we just need a full team to get through all the rounds. Anyone wanna help us get this achievement?
