in some instances, object overload is fun. For example, in the library's cache, you change the biped flood infection forms to biped flood carrier forms, whenever a flood carrier form explodes, it releases flood carrier forms.
I'm kind of suicidal on halo, so this seems fun to me
also, you can change biped cyborg to another biped character, and play as that character.
Unfortunately, if you do this mid-level at a checkpoint, the xbox panics and locks up
Same with if you set it to try and spawn things like skins... it doesn't like that either...
Still, the cache editor is a great and easy program to use, even for noobs like me
