Came across this game yesterday and have added to my steam wish list. Has a lot going for it but may need some time to iron out bugs etc. At the moment only Co-op and single player. so would need players ready to play before starting out, will see where this goes and hope private servers will be made available down the road. Check it out here: http://store.steampowered.com/app/444690 Will advise gameplay after purchase.
