grand theft auto four can only be played with one person on one console
I'm not sure, I know on Army of Two you can have your friend sign in as a "Xbox Live Guest" on his/her controller. Try that.
nope, if you have it on the computer and sign up to rockstar social club you can go on multiplayer
no
4 players can play through Xbox Live, but only 2 can play on the same Xbox 360 console.
yes -- on the same console up to 2 players on live--i think 4 players max
As long as both players have Xbox Live Gold you can play 2 seperate accounts on the same console on Zombies and Multiplayer.
you can check on the back of any original Xbox game, and it will say how many players can play on the Local Console (1-4) near the bottom right corner
its impossible to do it. to do it you would need two xbox 360s with xbox live its impossible
its the same as the one for the 360, its not xbox 360 live its xbox live thus working on both consoles.
unpluging your xbox has the same effect as turning the console off. you are disconected from xbox live but will reconect when you turn it back on.
yes, unfortunately you have to buy a separate xbox live membership for a different profile even though there on the same console.
if you mean the xbox pro console then of course you can you can go on live with any xbox console
yes if you are going Co-op and or on Ps3 online or xbox live.
No, I doubt that it has the same Xbox Live service as a console would but I'm sure it has some sort of Xbox Live applications such as downloading from the phone and then once the console is online, it will download those things you requested.
Any Xbox 360 console that has some for of memory unit, whether its internal or external, can use Xbox live.
