Next up on the budget Unity coop horror games list is Devour. It's about on the same tier as Phasmophobia in terms of polish and a bit behind in content (only one map so far, but it is large and they're working on another one with a different game mode) but it is cheaper. A friend gifted it to me and we went into it blind with 4 players and that was the right approach. You're part of a demon worship cult and you show up at your boss' house to find out what's gone wrong (hint: she's possessed, big time) and the objective is to herd goats to a ritual site and burn them to sever the link between her and the demon. Each goat you burn makes her a bit more aggressive and causes changes in the atmosphere for the darker. The only way to fend her off when she hunts for you is by using your magic flashlight's limited charge to stun her. There doesn't seem to be a limit to how many times you can get downed outside of how many medkits there are in the map for your buddies to revive you with. The sound design and graphics are good for the budget though the voice acting is iffy, they seem to have used amateur voice actors which is fine, but they also don't seem to be native English speakers, or doing weird accents. We got 7/10 goats before she picked us off one by one. There's definitely an optimal way to play by piling up the necessary resources before sacrifice so that you can get it done quickly. Going in the first time was a very unique experience with the fear of the unknown and figuring out what we were supposed to do; find hay, bring that hay to goats, pick them up while they're eating (initially thought we had to manually lure them), use gasoline the lit the pyre, etc.
