You are an engineer seized by enemy invasion during ultramodern arms testing of the armoured scaphander. Adversaries are everywhere. There is nothing left for you to do but beat off the numerous enemies. You will discover that your opponent is not so straightforward and is operating with somebody’s help... Make it through enemy fire to the end of the level. Use the mouse to fire and the arrow or WASD keys to move. When available select alternative weapons with the 1,2,3 keys.
