it needs 4gb harddrive or 8gb
You need the Halo 3:ODST campaign disk.
If you install it into you're hardrive then you don't need a disk at all. You simply access the game from the games section.
No. You either need to purchase it from the marketplace, or you can get the mythic disk when you buy Halo 3: ODST.
I am not quite sure what you mean by which cd. In the Halo Combat Evolved PC purchased package there is only 1 disk. That disk allows you to install the game and play the game as well. You only need that disk to do everything.
Getting the katana sword would mean you would have to unlock every achievement in the game. So you would need both the regular Halo 3 disk for the Campaign achievements and the mythic disk for the online and multiplayer achievements.
Deamon tools
Yes, all you need to do is install the game on an xbox.
No you don't , Halo :ODST is a stand alone game that has 2 disks : 1- ODST story mood and a multiplayer mood called firefight 2-A disk that has all the Halo 3 multiplayer maps that you can play WITHOUT the need to have the original Halo 3
If you mean do you need halo 3 to run Halo Reach then the answer is no. You can just buy a copy of Halo Reach pu it in your games console and play. I suggest if you do get it you get the limited edition one. Gamertag XBL: CODfatherSPUD
Umm... YEA!! also you can download a program dont ask me wich one idr but you can play without the disk
You would need the ethernet card can handle gigabit network traffic cable.
The need for a 10 Gigabit Ethernet for home office depends on the actual use case: for simple data exchange between different machines there most probably no need for 10 Gigabit - but if there's a use-case for video-streaming or other multi-media related tasks then a 10 Gigabit Ethernet network might be indicated.
