Blood is one of my all time favorites. It's a forgotten gem and I have not been able to find it online. Blood is a first person shooter like Doom. Throwing screenfull of enemies at you. The levels are what makes this game shine. levels were taken almost straight from horror movies such as The Shining, Friday the 13th, and others.
If anyone can find it let me know
