Cheat Title: 3 seconds
Entry Location: any level with hunters
Cheat: In any level jump on a hunters head for three seconds and wiil kiil it instantly.

GamesRadar: Our favorite part of this one is how it combines the instant kill with the prerequisite of standing on the head for three seconds. That makes our site the exclusive host of the world's first three-second instant kill.

Cheat Title: be a fish
Entry Location: anywhere where theres water
Cheat: Press the H button 47 times underwater and you turn into a fish

GamesRadar: Fish are the Master Chiefs of the sea. Ironically, though, you have to be a fish in order to hit the H button at all (we'll explain how that works in next week's HaloRadar). It's a catch-22 kind of a cheat.
