It's like a Dark Souls, but FPS. It has its degree of difficulty that is quite enjoyable (if you like Souls-like games), the graphics are quite good and detailed. Maybe it has its flaws when talking to NPCs, especially in cut scenes.

But the truth is that it is a game that is worth playing.

I run it on Linux Mint 21.1 Cinnamon and it runs very smoothly and so far without any glitches.
