So Call of Duty 4 is, how to say it... awesome. It's easily one of the best online multiplayer shooters I have ever played. Ever. Seriously. I stopped playing Halo 3 entirely for CoD4. I tried playing Halo 3 again. Played one match. Popped the disc out and went right back to CoD4. Its purely amazing.
So if you have a 360, get it. Play a few rounds with me. Gamertag's still TheFraggist.
