User Summary Orgamism is a sci-fi arcade action adventure game, an unoffical Alien game, for the Commodore 64 by Trevor Storey & Achim Volkers with soundtrack by Saul Cross. In the game the player explore the decks of the doomed transport ship Heracles and try to find a means of escape by finding pass-keys, data disks and terminals that will give you access to other areas on the ship. The players must look for crew-members that may have been infected by something that is lurking on the ship, something that the player must evade or destroy at all costs.
