Does this game have online multiplayer?

I've pretty sure I''m going to buy it, but I might buy a 4-pack for some friends if it has online instead of just local.

Yes.

While its most enjoyable in Local Coop, it has a fairly well working Online Multiplayer (some bugs might happen, but it gets better with every update).
I recommend playing with friends and communicating over voicechat,
because random people tend to get you killed a lot by being ruthless.

The main game does indeed have online multiplayer, though keep in mind that Deathmatch is restricted to local only.

Multiplayer is online, local, or mixed as long as the total number of people is between one and four. It does not have LAN multiplayer, though. People playing in the same room on different computers still need to go through Steam's servers to connect
