In Halo, I was trying to do another cheat and it didnt work but i found something else: On the last level (the Maw), you start out in a life pod launching area. It is tunnel like and small. Walk out of it and turn to your left into the other life pod launch area. After, go back into the area where you start out in and look out of the edge. You will see the monitor's machines that shoot orange lasers at you come up (and their wings are closed ) and they will come into the launch pad where you are but they wont shoot. You can either watch them fly by you or blow them up because they are defenseless. Note: They will turn around and shoot you when they get to the end of the tunnel.
