How to start a co-op game?

[freefall]

Hi guys, this is my first time with the MCC. I know this is kinda a dumb question, but I don't know how to start a co-op game. I see it listed under playlists, but I can't seem to find an option to enable co-op matching for single missions. So a few questions:

1. Which of the titles actually have co-op campaign play? Do I need to have the multiplayer components installed, assuming I'm only interested in campaign and not competitive matches? Currently I only have the campaigns installed.
2. Assuming the multiplayer packs are installed, how do I start a co-op game?

Thank very much in advance.

If you're talking about campaign Co-op, you have to manually invite someone to your lobby. There are no servers for public campaigns, you have to make your own lobby and invite people.

As far as how co-op is implemented in-game, you can generally play with three other players on Halo 3, ODST, Reach, and 4. Halos 1 and 2 are limited to one co-op partner. The net-code can also be questionable at times, but supposedly, 343i is trying to fix this and it only applies to a few games. The worse it'll reasonably get is slight input lag.

You also don't need the multiplayer packs to play campaign co-op. If you have the campaign packs, you have all the campaign content, including co-op. You can also play Firefight with the campaign content.

Hey, thanks for your reply. How would I set up a lobby? That means I'd need to have the player in my friends list first right?

Also, what is Firefight?

Sorry if the questions seem really noob, but I've only played Halo 3 co-op through split-screen back on the X360, and my first assumption that I'd find the co-op options through the Multiplayer settings.

Use can try using the Steam menus to invite people or try using the Xbox game bar to invite people by their Microsoft account.

Firefight is technically a multiplayer game mode for Halo ODST and Halo Reach. It's basically a horde mode where you hold out against the Covenant. It's pretty fun if you just want to kill normal campaign enemies.

Hey, thanks again for your input, really appreciate it. I'll give it a try tomorrow and see how it goes (it's pretty late for me here currently).
