Yo natch you are way behind I don't wanna explain it all for u but check out other forums for more details. Here's the upshot. There are hacks for COD4. Don't get too excited though because there patched. However if you delete the GAME DATA (the patch) than you can play with them in Single Player and Splitscreen because you can't play online without the patch. If you wanna know how to do the hacks, there's like 30 forums on it in Call of Duty 4 Exploits and Hacks. Wow that was too much writing for me. You're lucky that I wrote this much.
