My friends and I are making this game called Neighborhorde.
It's a twin-stick, couch co-op, shoot em up, horde mode game. We wanted to make a game that brought people together under one roof, so that's what we're trying to do.
Here's the Greenlight page if you want to check it out: http://steamcommunity.com/sharedfiles/filedetails/?id=547748300
Would love to hear any thoughts!
