Blood was a great game.
I remember finishing the whole thing!
You could decide if you want to use up a whole can of spraypaint as a bomb or use it little by little as a flamethrower.
There were little spots in the game that were callbacks from movies and other stuff.
I remember you could find the frozen corpse of the guy from the Shining in a maze and find Jason's shack from Friday the 13th. And then Caleb would say something funny.
Great game. I hope this FPS is half as good.
