Of course. That would be ridiculous otherwise.
Steam. Its a program that allows you to download PC games. If your on xbox or ps3 you have to buy it in store or in the PSN or XBL stores.
Don't stink at multiplayer...
Yes. Four player split-screen local Multiplayer.
Yes Call of Duty 3 does, if you meant MW3 then no but it is on ps3, xbox 360, pc, wii, and even the DS (not 3DS though)
I dont think so, if online then no.
The multiplayer mw3 server automatically chooses you. You dont know when you are the host. It is just randomly chosen.
Simply go on multiplayer then click local and finally click split screen.
MW3 has terrible graphics but a good campaign, but black ops 2 has good graphics multiplayer and an awesome story. Plus it has zombie mode. Go with black ops 2
Of course. How could they forget the PC gamers?
under store in the multiplayer menu
No. Just Spec Ops.
