hey this cheat allows you to be invinceable.
when you collect an over-shield it takes about 4 seconds for it to go up, at that very moment in time you are invinceable YES !!!!!!
you can try grinage jumping with it and get really high and try it with a warthog, just park it next to a over shield do the grinage jump to the warthog and then grab the over shield and jump in the warthog you have to time it just right.
i will be makeing a movie on it soon so stick around for it !!!!!!!!!!
OHHHH yer one more thing.
i will show you how to get your marines stuck in a tree how bout that LOL!
