CO-OP Question

yeah, doubt it'll have problems on co-op since dunno, they gonna focus a bit more on the co-op side with all the spartan ops misions right?

the only question I have in mind, is what characters will the 2nd 3rd and 4th player be on campaign co-op

Please post any in-game related question, to the forum relevant to it, or in the "playing my game" forum.

The game does not feature co-op in campaign, it has co-op in the Spec Ops side missions only.

I have been having the same problem for the last two days in the morning but in the evening I am able to do it just fine so I am not sure what is going on

Here is some info from the developer:

Inviting through Party:

1. Ensure you and your buddy are in a party of 2 together.
   
2. If you’re sending the invite, make sure you’re in game and have already gotten to Rhonda’s garage. Co-op is available from this point.
   
3. To send the invite, pause the game, and select “Invite Party to Game” (This player will play as Nick).
   
4. At this point the other player will be brought into the first player’s game as ***. Commence zombie killing!
   
   
   
   Using Matchmaking:
   

1. When starting a new game, you select a “Play Style” which will be used to match you with like-minded players.
   
2. Selecting any Play Style other than “Single Player” will make your game available for matchmaking.
   
3. After reaching Rhonda’s garage, if there are players searching for a game with your selected Play Style they will be matched with you.
   
4. If you would like to play Online as *** in another person’s game, select “Multiplayer” from the Online menu, then choose your Game Mode and Play Style to search for a game session.
   
5. If you like, you can load your own single player save game and play until an appropriate session is found.
   

Yes, and it's a very good campaign too!
