Nightmare Fuel: Campus Life
Slenderman was the scourge of Smash Campus, hunting poor students and killing/eating them before leaving back to his secret hideout. Nobody was brave enough to stand up to the monster until Lara Croft returned from her self imposed exile and confronted him. The resulting battle involved Slenderman stealing and scattering Lara's weapons around the temple, forcing her to traverse deadly booby trapped rooms to recover them before finally facing off with Slenderman himself. After a hard fought battle, Lara kills him for good and takes his regenerating Healing Factor before going back to Smash Campus.
