(adsbygoogle = window.adsbygoogle || []).push({}); I have cfw, probably CEX. I've never played MW3 or been here. How do I host lobbies for my friends?

You have a few options. If you just want xp lobbies, with fun things like super speed, force host, unlimited ammo and so on I suggest you just use a modified eboot. If you want godmode and so on, your going to need a rtm tool.
