No
keep playing the campaign or if you want a rank online then play online
Sadly no, you cannot play with other people other then online i dont know why the case says that you can.
yes you can just go onto multiplayer and make an account and play away!
Yes, you can play cooperatively on either splitscreen or online.
yes you can with up to 4 people its awesome
Yes, you can play cod5 with 2 players in a campaign.
The game is single player and online multiplayer
You can play it on splitscreen or with XboxLive
Nope unfortunately you have to play splitscreen online, halo wars has waaay to much stuff on screen to handle as it is, double it and something would blow up :)
If you like to roam free and and fool around gta4 is what you need. But if you are a serious gamer who likes to rank up and loves online play get cod5.
Sorry, you need a copy of CoD5 to play it, and first you need to beat the campaign on any difficulty.
