I'm assuming you mean a LAN party. For a LAN party, you have to have multiple Xbox 360s and multiple TVs. Hook each Xbox up to a TV normally, and then connect an ethernet cord from each Xbox to the ports on the back of your router. Once this is complete with however many Xbox 360s you are going to use, start Halo 3 or Halo: Reach on all the systems. Once this is completed, change the network type to LAN for all systems involved (there can be a max of 4 systems with a max of 4 players per system). After this, it should be pretty self-explanatory to get the other systems into the lobby. I think it just automatically finds the lobby, or you have to select the network or something. I've only done this once. I know the first part is correct, but I'm just not exactly sure what it does once you switch all the consoles to LAN.
NOTE: You cannot play via Xbox Live if you are hosting a LAN party. All systems and TVs must be at your house, connected to your router.
Hope this helps!
Halo 3: ODST is the newest of the two, but not the newest Halo game.
go to multyplayer and press system link then go to host or start a game
Halo 3?
it goes halo, halo 2, halo 3, halo 3 odst and soon halo reach will be available
halo 3
halo 3 odst
halo 1,2,and 3
(the second best game in the world) The third game in the halo game series
Yes, HALO 3 ODST and HALO REACH have been made
Well, it is an entirely new game, so proably not. But the game will come with halo 3...
If you mean any Halo game period, then its easily Halo Wars. If you mean a Halo game made by Bungie, then it would be Halo 3: ODST.
no halo 3 is strictly a xbox 360 game
