Bungie has a few xbox360 servers hosting modded gamer tags also rigged with modded service records, achievements, and animated gamer pictures [don't bugg me to tell you because the only hint you get is Traxus]. -- But that's beside the point.
This could be possible you just need some programs to run on your computer to take care of whats needed to be done for example cycle trough maps. The computer will need to take control over a controller to switch maps.
To control an xbox360 with a computer is easy, you have the input to the computer via capture card... the computer controllers that xbox with a thing called a "Xim360".
A xim360 is a modded controller where it is rigged to be controller via keyboard and mouse from your computer. My buddy t0p8uZz and I were discussing about a robot that plays games on the xbox. But having a glitched CODMW2 xbox360 server sounds much easier to program AND you could snatch some M$ Points from people, lol charge them 1600 for a 24 hour session!
Hey just explain how the Hardcore mode rank glitch works (I don't play COD but i know the basics).
