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.

Better than the first mission pack but has some really annoying bits.
