If you refer to my previous review on Blake Stone Aliens of Gold, you will find that was my first FPS game I ever played. This one was remarkably different, but keeping the same style as the first Blake Stone game. It had a lot of new improvements, such as adding new weapons, instead of getting a red keycard to exit the level you had to blow up the power conduit that would open the gate. The atmosphere had also dramatically changed, adding a sort of fog-like effect to the aging Wolf3D engine. A must buy if you loved the first Blake Stone, and also Wolf3D!
