how much memory does xbox live need/
When referring to memory you need to be more specific. Do you mean usable memory (RAM) or do you mean storage (Hard Drive). An Xbox comes with a set amount of Ram, not upgradable. The Hard Drive can be upgraded to a larger drive(very expensive). All games that are made for the Xbox will run on any Xbox( no compatibility problems.
8 GB
y dose it matter..get off xbox..
No it dosent need a memory card
you probably don't need Xbox Live for beast mode, just as you didn't need Live for horde mode on Gears 2
Yes. You need to buy a special memory hardware for xbox to exchange the memory
The Xbox 360 needs memory because it doesnt have a memory unit installed and it needs memory for gamer profiles and games.
Gears 3 does in fact need xbox live to play multiplayer, but not for experience. Also, you can play multiplayer locally on Gears of War 3 via system link or on 1 console.
You do not need Live to play horde.
you cant because the game cube does not have as much memory as a ps2 or xbox.
Only if your Xbox 360 hasn't got a hard drive.
