Can You Play MultyPlayer OffLine?

[Chripper!]

You see I go online on my "bad computer" and play halo on my "good computer" the problem is my good computer doesnt have the internet but its the only computer that can play halo, can I play multiplayer offline.
(Note; Im asking this question because I havn't got halo yet (on pc) to see if I can.
I need to use it for uploading maps.

yu can play multiplayer on it es, jsut go to create a game but under the option for that, click create a lan game.

[Cheeze Man]

you acn play halo through LAN or use a LAN to share a connection, otherwise NO

[DECOY]

you can run a multiplayer map as a Lan game. If you download a mod that has AI in a multiplayer map, you have to play it as a Lan game by yourself as the AI doesn't sync online with the other players.
