You are in the forest where there is an abandonded asylum, in which there used be done numerous and various experiments to people and animals. Now you have to face all the experiments, as they rule this forest. You have 5 weapons. 1 pistol, 1 shotgun, 1 burst mode smg, 1 auto riffle and 1 sniper. You also have a flashlight that decays its light and for which you need to search for its batteries in the forest, in order to have as much as visibility you need.
