Download Tarzan: Guardian Of Earth
Tarzan: Guardian of Earth is a 3D game released by Seth A. Robinson in which your main goal is to start fires all over the jungle by peeing on the ground. It sound silly, but this game is all about urinating on trees in order to put out lightning fires and when you run out of pee in your bladder, you have to search Pepsi cans or CoolAid to drink.
Press the W, A, S and D keys to move in different directions through the jungle and then click the left mouse button to pee on a tree. If you want to jump over an obstacle, press the Space key.
