You are the ultimate prototype resulting from an experiment created to take out the aliens by infiltrating their base. Select from 2 characters and enter the enemy base to destroy the aliens. The platform is filled with traps and spikes that you will have to avoid. Use your WASD keys to move around and the space key to shoot your machine gun. If you get hit by the enemy fire or the enemy itself, you will loose health. Your health bar is shown to the top of the screen. Find your way around by exploring the base and destroy all the hostiles to complete the challenge.
