Sounds like it wont interfere with the single player experience. Glad to hear it!
Judging by what they’ve said about it, the co-op multiplayer would be in the same style as minecraft. In that the world and everything in it is exactly the same, the only difference is that you have a friend in there playing with you!
Well I just wanted to let you guys know what it says like on it is worded and such on Green Light. You gotta remember people will take literally what you say about things. Like I had thought it had coop from the start since that is the way it was worded and had the tags on Steam Green Light. I am looking forward to this game, but I just know how the people on Steam can be so just wanted to basically give you the heads up. Valve has no problem taking your stuff down.
