Again we're a little behind (a little less this time, though!) on getting this one out, but hey, better late than never I suppose!
Fall of Anterfold (or AnterFOLD, it's used interchangeably), a colorful-equine-flavored co-op survival horror game, has recently released its second beta. According to their website, there seems to be quite a few interesting rules in place, such as a shared life between two players; if you or your partner die, that's an automatic game over. They also tout the general ruleset changing between games, such as shifting the amount of loot and enemies. Overall, it looks pretty interesting, so do check it out!
oh and merry christmas i guess that's a thing that's happening right now
