Two for One: Kill 2 people with one Spartan Laser blast. For those who haven't played Halo 3, the Spartan Laser is a huge well... laser that takes a few seconds to charge up so to kill two people they need to be right next to each other or in a line. Very tough.

Mongoose Mowdown: The mongoose is basically a small ATV making it easy to dodge or jump over plus to actually kill someone you have to be going full speed. I spent a whole match just driving around on a mongoose to get it and got lucky.

Overkill: Get 4 kills within 4 seconds. Sounds easy right? Maybe in a 10 player game but in FFA killing 4 people means killing EVERY OTHER PLAYER in the game. Really only possible in oddball or king of the hill unless you get super lucky in a slayer match.

Steppin' Razor: Get a triple kill with the sword. Yep, once again kill the majority of the players in the game, at melee range no less.

Maybe Next Time, Buddy: I like this one, after having your vehicle jacked, you have to jack it again within 10 seconds.
