By some chance are there horror games with combat mechanics on itch.io?
idk are all of those on itch but deppart prototype Has great and VERY immersive shooting, lamentum has some combat, Spooky's Jumpscare Mansion in later gameplay has some simple combat, Lost In Vivo has shooting too
oh my what offer but what about something underrated like the breed on itch.io exclusively.
Buckshot Roulette might be your speed. It isn't free, but definitely worth the $2.99 price.
thanks for the offer but buckshot roulette is not so much combat focus since having the shotgun is part of the roulette gimmick of the game after all.
