Heard really good things about this one!
Short version: Left 4 Dead, but against rat people in a fantasy setting, instead of zombies.
Thanks to https://www.fimfiction.net/user/199165/ZeroOneInFinn for the info.
Don't worry, there's still zombies! Although they're still technically aware... But yeah great game definitely recommend
Thanks.
