Under key features: Four-player co-op multiplayer - explore with your friends!

Just wanted to chime in and point out it does have 4 person c0-op play and rift support.

It's right there:

It's amazing how you gained enough from early-alpha footage to both criticize and insult those who are making this game! You are a rare breed of dick and moron!

It's up to four player co-op. It was one of the stretch goals on the Kickstarter, which made 3 times what he was asking. I backed it and have been looking forward to playing it hopefully soon.

I know the guy working on this and he's super smart. I was not surprised to see what he was coming up with.
