Before Xbox live started we had to gather our Xboxes, get the system link ready and separate the room with a sheet. We were playing 4v4 all night long and were playing the tie breaking 21 on Blood Gulch . Down 46 to 49, I just got to their base with a Magnum and Plasma Pistol. After killing the first with my magnum I was jumped from behind with only plasma ammo left. They came at me one by one while I slowed them with the plasma and circled behind them for the melee kill. Quad kill, 50-49, game over.
