On Saturday I went to gamestop to trade in some games, and I wanted a good first person shooter to play. I ended up picking up COD4: Game of the Year Edition. I played the single player for awhile on Sat, and the multiplayer that night and on Sunday. I am really enjoying the game so far. The multiplayer is really fantastic. I love the way that you unlock new weapon attachments, camo, perks, sights, and weapons, (primary, sidearm, and support). I am like level 12 right now I think, and I’m using an m16 with a red dot sight (which is a major improvement over the sight the gun comes with).
