A dodge-em and blast-em type game set in outer space.
Your space pod descends from its mothership at the top left of the screen. This must be manoeuvred through debris that continually crosses its path until in line with an alien space craft and its cargo. After blasting the alien and collecting its treasure, you return to the mothership before your pod's fuel runs out. This continues until all cargo has been collected. The number of these depend on the rounds completed, there being five in all. After ever round an alien control ship appears which must be blasted six times in succession to destroy it.
Points are awarded for the number of cargoes collected and ships destroyed as multiples of rounds played and skill level adopted. There is a choice of five skill levels. Extended Basic and joystick are needed.
At the end of a game the score is given and if sufficiently high you enter the Hall of Fame. Here there is an option to save and load your high scores on file. Unfortunately the scoring system of the game is at fault as in all following games, the program fails to reset to zero.
