I played XBLA with just alien weapons on this map, and to my surprise, it was the most fun multiplayer game I've ever played. That's not saying much, since, you know. You all are... You know.
Did you know that Pi backwards is Pie? 3.14- 4=P, 1=I, 3=E. Anyway, I actually recommend playing with Dead Players Drop Items, because the minimum count of guns here is half as much as the total count.
