Sweet. Yeah, I have several, but most can be gotten by stacking them. I sent you a friend request on Live. I actually tested changing my language on my 360 and there are a lot of ppl playing using most those languages (ie: Chinese, Russian, etc). More than 6 ppl would be even better, and we'd all need to press "start matchmaking" simultaneously.
So here's the plan..
Overkill (preferrably w/ sword) + 5 grenade sticks + spartan laser double kill, yields: overkill, triple kill, steppin' razor, killing frenzy, lee r wilson, two for one. Then find a map with vehicles to do the last two. We could even try to even out the score at the end to prevent rank loss.
Well, I know that you can form an Xbox LIVE party for chat without forming a Halo party, so I'm gonna guess that it is possible. Huh, that's interesting. I'll help you out with that sometime if we can make it work. I've got 4 that I need to get still myself.
