Halo 3 campaign lobby open

Play the Campaign. The game just came out on Tuesday and when I tried no one was in or joining the lobbies. They should have a it up and running properly by the weekend. It's like Halo 1 Halo 2 Halo 3 Halo 4 running on one game so they may need some time
to sort out the servers.

I'm still having a blast with the campaign, which is what all my friends on X1 are playing in Halo MCC. CE looks way better than CE Anniversary on 360. I just started Halo 2 campaign and that looks 'awesomeness' too. One of my friends decided to use that
word so I thought I'd copy her.

As for multiplayer, yes Microsoft needs to sort that out. Xbox 1 is about seamless lobbies like in Forza not waiting in a lobby for an hour then giving up.... has anyone does this? I've tried a bunch of different lobbies and after 3 minutes I just go back
to campaign. At least you're playing with AI... it's somewhat like playing with real people.... I guess....

By the sounds of it, you bought Halo 3 Mythic off your friend and not the retail copy of Halo 3.

Halo 3 Mythic only features the Multiplayer aspects of Halo 3 including all 24 Halo 3 maps.

Campaign does not come with Halo 3 Mythic, you will have to buy a proper copy of Halo 3 for Campaign.

Campaign - Halo 2 and 3

Multiplayer - Halo 3 and 2
