There are a lot to sift through, but I recommend:
- Nightmare Reaper You play as a woman sent to an asylum and the battle is against the horrors within her head. It has tons of fun weapons, enemies, and challenges.
- AMID EVIL A magic themed FPS that reminds me a lot of Hexen/Hexic. It has a superb soundtrack.
- Forgive Me Father A horrific adventure to fight a cult and its otherworldly summonings. Has a perk progression system that sets it apart from most.
