I can understand that. In lockout, they allow'd you to spawn a banshee in the middle, and at the bottom of the gravity lift there is a human turret.
Goddamn, we ended up playing slayer with 300 overshields and regular weapons for about 45mins with only three people. It was fun shit. At the very end, I took the banshee to the very top of the structure and I figured out that I can land it in a certain spot to where it would shake causing it not to respawn automatically. I waited until I had max sniper rounds and got a energy sword and went up there and was sniping the other two guys while they were shooting each other. Takes about three headshots with 300 shields to kill someone though (which makes sense). After I would run out of ammo and nades, I would switch to ES (since I had no other ammo) and swoop down to the sniper rifle pickup. I had some VERY close encounters doing such as the ES is not like it is in the retail.
