Had my best round yet! Big Team Battle CTF. Had a 16-kill streak at one point, as I was death incarnate in a Warthog both splattering enemies, and gunning them down. It was sort of funny. At one point, the flag carrier kept running even though we were honking at him constantly to get in the Warthog. But that helped my kill count as the enemy kept trying to gun down the flag carrier.
What finally ended my reign of terror was the enemy warthog slamming into a crate, which slammed into me. Ah, Halo.
