Well on the fact Call of Duty is the most popular Console based game if it didnt have online no one would buy it.
Yes it does. it also has new map packs and nazi Zombies online, not to mention co-op campaign online
If you alredy have PS3 online account, just go to multiplayer, then press online.
they are less than with the Xbox 360 or PS3 but you can play online multiplayer with the Wii
Yes you can
Yes, you can for free but currently the PlayStation Network is down
You can only play online for free with a PS3 or xbox360 or a wii. So make an account go to your call of duty game and go to multiplayer go to online connect and there you go your on online mode
The Call of Duty World at War Final Fronts for the PS2 does not have multiplayer available. If you want multiplayer for World at War you need get a PS3
yes it is for single player offline and multiplayer online if by classic you mean Call of Duty 3 see related link
For the PS3 you have to buy a wireless router then u connect it to your computer. After that you connect it to your PS3.
of course on multiplayer
Call of Duty 4 is available on PS3, Xbox 360, and PC. It has split-screen multiplayer (up to 4 players) and online multiplayer (up to 18 players) as well as a single player campaign.
I think you have to update the game online or somthing like that.
