I recently got Call of Duty4: Modern Warfare. I loved the game! Just got started playing online and weird things started happening. Like all of a sudden I was Commander level 55 with all the weapons and stuff. I reset in Prestige mode cuz I wanted to go through it myself and not cheat. At around level 7 or 8 I jumped up again, I reset again. I logged out so my roommate can play and he could not log in to multiplayer menus. I checked mine and same thing. I got on line to look for info and found out that the COD4: MW multiplayer software online has been so severely hacked that it can render your purchased copy worthless.
Anyway, although an excellent game, for multiplayer I suggest staying away from COD4: MW.
Alot of server host migrations
zombies is good but most have the DLCs so you might want to get those mainly so you can also get multiplayer maps.
wasent laggy for me and yes there are always morons on COD
It may not be laggy for you, but it is for others. Like the lag i run into is where i seem to get hit only once and die, but when you see the killcam, it is legit. I also have been on the team that is not lagging and you feel like a hacker lol. But i didnt mean every game is laggy. Sorry for the confusion.
