Multiplayer Halo 3 Missions In Xbox 360?

[Pokoron]

The limit to play a mission in Halo 3 in two people in the Xbox 360, right? Because I saw videos that there more than 2 people playing a mission. If so, how can you do it?

you can play up to four people in halo 3 missions. you just go to the campaign lobby and plug in four controllers and sign your account and for the other three controllers just press the guide button(big middle button)
then u sign the other there as guest. Or if you have xbox live you can play with other people online all u have to do is give them a game invite. If you stilll have problems my gamertag is DA OG SPARTAN

Nah your wrong. Up to 16 people can play with you in a campaign game all You have to do is round them up and invite them to your game.

But you can only play with up to 4 people on co-op offline.
