TSA writes: You might notice that Graven sounds a lot like Hexen, and thats probably deliberate. Touted a spiritual successor to the 1995 dark fantasy FPS, I was tempted to just look up some details and run with it in a vaguely official sounding games writer tone for a bit, but truthfully, I never played Hexen. I jumped into Graven because it looked a bit like Monoliths 1997 game Blood and a bit like David Szymanskis 2018 game Dusk. Its not actually entirely like either of those games, but if the hour long demo is representative it is bloody excellent.
