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.
No
The xbox hardrive is a bit more difficult to use than a PC hardrive. take these steps if you downloaded it from the marketplace: 1.go to "manage my account" 2. go to "download history" 3. select it, and you can re-download it for free. don't worry the same thing happened to me.
2, The Xbox and the Xbox 360.
No, you have to give it to a friend online, then go to your other account and get it back from there.
If you mean two account playing on the same xbox then yes.

If you have xbox then you need an xbox live account or if you have PS3 you need a PSN account. Then go on multiplayer and select play online.
They are from the pc, online xbox live account. What ever achievements you earn from that game goes to your xbox live account's gamerscore and be classified as "Halo 2: PC".
If for Xbox 360 you need an Xbox Live account, for PS3 you need a PSN account, and for both you need the internet connected to the console.
make an account on bungie.net using the same email and password as you used to make your xbox live account and go to community files and search modded maps
for co-op/non xbox live only 2 profiles at a time (on the same xbox) can be used, though for xbox live, 2 teams of 5 play each other, and on horde it is just one team of 5
Yes, you can play cooperatively with a buddy over Xbox live, or on the same Xbox.
One person may be signed on per controller, but not with the same profile. If you need someone else to be signed on to play xbox live, many games have a "guest" option that allow a controller to be signed on as a live account's guest.
Yea. You just need 2 controllers, one for each account, and just sign in normally with both controllers.
As long as both players have Xbox Live Gold you can play 2 seperate accounts on the same console on Zombies and Multiplayer.
