Modding Halo 3... Are there any ??

I was wondering if there is any or if some one has made one??

 

Yup but you need a jtag to do any mods for the gameplay where as theater you can AIO mod that and recon if you dont sign up to bungie

 

i can mod your campign save. extract your personalxxxxxxxxxxxxxx file and send it to me. see my post about mods that can be done.
