You know what's funny is I now know how to destroy anyone that wants to horde the sword room on the pit. Everyone always throws grenades around the corner when there is a MUCH easier way to do it. Lob grenades through the ceiling and they go right into the sword room and voila! You see "You killed XXX" and you clear out that sword room REAL quick!

Tactics. Get one guy on the blue spawn side and one guy on the red spawn side of the sword room, both chuck 2-4 grenades through the ceiling opening and BOOM! many deaths.
