You're in an alien mission and you have to kill all the creatures before they kill you. Move with WASD, use nitro with F, aim with your mouse and shoot with space bar.
Drive a big cutter truck, go to the marked place and destroy the right elements. Use arrow keys to drive, space bar to brake, Z to cut the trees. Don't injure the animals.
Use the arrows to drive your car. Avoid the vehicles in the opposite direction and pick up the magic potions to score points. Press the spacebar to jump.
