It's pretty cool, it's like a metroidvania FPS. Playing on Pharaoh difficulty had some levels be pretty frustrating but overall I enjoyed my time with the game.

Go to PC gaming wiki and download the patch for the game, I only crashed once. It's a mostly fun game that I can't complain too much since I got it for $3~. Majority of the levels are fine, though in chapter 3 there are a couple that are way too open and long with too many enemies. Is this game the Daikatana killer? Maybe. Fun soundtrack too.
