The Anastasia ship is attacked by the Treens as soon as Dan steps onto it, although fortunately he picks up a laser on board. From then on, he must act as fast as possible. The main task is to find each of the 5 parts of a planetary-destruction mechanism to the control room, so that it can be safely diffused. He can only carry one at a time, and once he gets the back he must find the correct socket for each one. Lastly he must escape to the surface. Contact with a Treen will see Dan kidnapped and placed in the prison area; he can get out easily enough, but will now be in a different place. Getting hit by gun blasts will weaken him gradually.
