It is based on the game and what is allowed with the game. You have to choose a game that allows it if you want to play online with a friend on your Xbox 360. The same answer does apply to the Wii and PS3
All games have access to Xbox Live; it's just a matter of the multiplayer, and Assassin's Creed 2 does not have multiplayer.
As long as both players have Xbox Live Gold you can play 2 seperate accounts on the same console on Zombies and Multiplayer.
There is no Xbox Live multiplayer for Guitar Hero 2. But you should still be able to sign into live if you have all of the updates for Guitar Hero 2.
Sadly... no. You can play Special Ops multiplayer, Xbox Live and split screen. And you can play Xbox Live, Xbox Live but not split screen
If by Xbox Live you mean Multiplayer then no. There is no online Multiplayer for Mass Effect 2. ME2 is strictly a single player game. But, you can be connected to Xbox Live and get exclusive offers and DLC's via the XBL Marketplace, that are hard to pass up (if you can pay the price for them :P)
I'm pretty sure you can... I know for sure you can on CoD BLOPs.
if u look on the back of the box it will say 1-4 people.hope this helped
Call of Duty 3 first of all needs to have the ability for online multiplayer gaming, (which it does). It also has to be able to handle multiple people on the same xbox 360 console and at the same time being able to play online multiplayer. Halo 2 for example can have 4 people playing on the same xbox console and at the same time connecting to other xbox consoles for online multiplayer gaming. If the game can do this, you must also have 2 different xbox live accounts. You can not use a guest off of another account as an xbox live account because the guests do not have the ability to talk through a mic, even if you have 2 mics. If you have 2 xbox live accounts, then the two of you on the same console can talk to other players on xbox live as long as you both have separate accounts, controllers, and mics.
No
yes. you need live to play any game over xbox's internet like system for anything multiplayer with people outside of your own home.
Yes you can. I saw that its better than playing it on the xbox. But multiplayer is a little hard to get for many people.
Not on the same console..but you can play regular multiplayer (of course) and special ops (with up to 4 ppl i think)
