If you and a group of your friends regularly play co-op games together, this is a must have for you (voice chat is a must). You've heard of first person shooter games? Well, folks, this is a first person cleaner game; the shooting has happened, the world is saved, and you are the janitorial staff tasked with cleanup. I have never hated saviors of mankind as much as I have while picking up their discarded ammo casings and fixing bullet holes in the walls.
Reasons why it's great for co-op:
1. The satisfaction you and your friends get when seeing actual progress in transforming the unique environment of the game you're playing. Seriously, this sounds weird, but we feel great seeing what we had to work with and what we made it into. I never expected to enjoy playing the game as much as I did and I was shocked at how much fun the friends I gave my four pack to liked it.
2. Hearing them argue about the best methods to dispose of a body (record for blackmail later!).
3. Seeing them walk into a room, look up, and exclaim, "Oh god...HOW IS THAT EVEN POSSIBLE?!"
Early Access Tips:
Remember, if you play the game now, it's not going to be at its best. Early access means it's rough and there's definitely some code optimization and collision detection going on that can be frustrating (and sometimes funny as hell) to work with.
When hosting a game, it's a direct connect type. So make sure the person hosting has a pretty decent computer and a solid internet connection. If you can't connect to their sever, they may need to setup port forwarding. The ports used by this game are 7777 and 27015
If you get a "too many actors" error message on your server, it means there's too many unique items. This can happen from tracking too many player bloody footprints around. Happened a lot when we were doing a 4-man cleanup team. To solve this, have someone get rid of all the ammo casings on the ground (pick up and drop in the incinerator) and the rest of the group should focus on getting a specific area of floor clean. Of all blood and gore. To prevent this from happening (until it gets fixed) try making little clear footpaths to all the necessary machines (incinerator & bucket maker).
