If you are talking about the Dev Trainer for Halo PC & CE:You have to exit out of Halo, then exit out of the Dev Trainer. When you restart Halo (the dev trainer should not be opened), the dev trainer will not be controlling Halo. OLD ANSWER:i don't think u can....but it would depend on which 1 u have.try (when your consle is up)pressing tag(that brins up all optoins)debug then press tab,or cheat then press tab.hope that helps!!!

No, but you could always use a trainer
I recommend Dev Trainer for Halo just search it up on youtube and download it is quite good
First of all, you have to have a modded xbox console. Then you need to copy the Halo 2 game to the hard drive, itself and download the Yelo Trainer. This is ran by XBMC (Xbox Media Center).
halo 3 odst
Penguin storm is the best CP trainer. You can get it at cpcheats.info.
There is no best in Halo 3. There can be a team that is the best, but know single person is the "best".
