somehow transfer a mod game (Halo) into your actual game?

you are not supposes to do this and will get banned from xbox live but you must have a couple of basic things double 007 agent under fire or splintercell non platinum edition you need action replay and you need mods made through dothalo or downloaded this being a long process i will sum it up you use dothalo to put your mods avalible for download through actionreplay it then lets you dowload your mods into halo through the download new content feature i am not endorsing this it is against rules you will get banned and it is cheating thankyou and goodbye

you need to go through your program files and find the halo folder. then you make a copy of the un modded map (just in case you want a new mod or no mod at all later) and then delete the origional and put your new one in its placeits been a while since ive last done this but i believe thats how its done
