Is this possible?

Is it possible to have two people on my xbox 360 to then play online against other people at the same time?

[Wootzeh]

On certain games e.g. Gears Of war and halo.

[Mario]

Yeah, it all depends on the game

[GhostFace-]

yea like others said depends on a game/ game mode.

example:

on halo you can play online on normal matches but not ranked.

What about on cod4?

[mangle]

i think there is a way , play split screen and take it online.

i played with two dudes with the same tag , one had a -1 at the end though.

What about on cod4?
Nope, Cod you can't which really sucked when I found out.

I'm aware Halo3 and PGR4 can go online with multi player consoles, beyond that I don't know.

COD4, Ace Combat 6 and UNO I can confirm don't allow it :P
