I might be open on friday but definitly on the weekends, I would like to get it done early so we dont finish at 1 a.m. the next day. I would prefer if we used this tip I got from a forum on here and it works pretty well. It is on Alpha Site and we just go inside of the elevator and hit the body parts that stick through the glass. Grenades are no problem they just bounce right back at them so the covenant basicly kill themselves. When the hammer cheiftans start to come that is when we run like hell lol. The drones are taken care of by the SMG's they are very effective. And we need two guys by the stair cases to shoot the hunters in the backs while they try patheticly to hit us through glass (because their backs show and they wont pay attention to them.). Just try not to fall off the edge so avoid jumping. AT THE BEGINNING WE SHUT THE ELEVATOR ENTRANCE SO THE BRUTES AND GRUNTS CANT COME IN OR THROW GRENADES THROUGH THE DOOR And to add to my point they cant come through unless they are pushed through somehow. Read this and make sure you follow it precisely. Try not to die ;D
