There is an offline multiplayer (splitscreen) option yes.
You can play with up to 4 players.
You cant, 2 players on Halo Wars is only online, if you do not have Xbox Live, you will not be able to play 2 players.
unfortunately you cant i wish they could of made a splitscreen but they didn't so it is either one player or xbox live match sorry
You can only do campaign, forge and custom games without xbox live. You cannot do any kind of matchmaking on Halo without xbox live.
You need Xbox live gold membership to do so. Sometimes Microsoft will allow silver members to play online on a weekend.
U Dont
Yes, there is online multiplayer on Call of Duty 4: Modern Warfare.
U go to multiplayer if no multiplayer u beat
Call of Duty World at War, Modern Warfare, Modern Warfare 2, Black Ops, and Modern Warfare 3 all have online multiplayer.
Yes You Can
Unfortunately no, you can't play multiplayer on Call of Duty Modern Warfare 1 or on Call of Duty Modern Warfare 2 on the same screen. But on Call of Duty Modern Warfare 3 and Call of Duty Modern Warfare Black Ops you can play multiplayer on the same screen. There is an new Call of Duty Black Ops 2 coming out soon though, so I expect that to also have that feature, since its newer.
There are a total of 70 levels (ranks) in Modern Warfare 2 Multiplayer.
No you can't.
Sadly no.
no, but there is call of duty reflex, a remake of CoD4 with multiplayer.
No. There is only Nintendo WFC.
Multiplayer is free.
I would say that Call of Duty: Modern Warfare 2 is better, because of the weapon selection, perk selection, graphics, gameplay - both multiplayer and singleplayer storyline, the killstreak reward selection, the offline multiplayer class customization feature, and the online multiplayer gameplay. Everything about Modern Warfare 2 is better. Except the price.
