Looking a lot like a classic Resident Evil game but switching things up to be turn-based, with dungeon exploration - House of Necrosis looks genuinely very cool. It will have Native Linux support and a demo is available right now, with the release date recently announced to be October 6th.
What a lovely unique blending of genres we have here. Indie developers really do come up with some wild combos.
Check out the brand new trailer for it below:
