Team SWAT. 4 vs 2. Just me and some random French dude on Ghost Town versus a team of reds. That made me angry. And you won't like him when he's angry.

Oh yeah, I'm badass.
You are officially the Incredible Hulk.
Uh, I haven't played halo in ages. I think my entire team left during a game of team snipers, but that didn't make me angry. Winning 50 - 6 is always fun.
Was going for a quad kill when my teammate came up behind me, shot at rocket at the ppl I was trying to kill, and ended up killing me. I would've had the Overkill acheviement too.
If you had a teammate, that implies you were in a team games, thus you wouldn't have got the Overkill achievement. The achievement is for Lone Wolves only.
