星十字 Starcross

Starcross is a science-fiction text adventure set in 2186. Humanity has established settlements across the Solar System and uses captured quantum black holes as an important source of energy. The player is the sole crew member of the M.C.S. Starcross, a small prospecting ship searching the asteroid belt for an undiscovered black hole valuable enough to repay the cost of the expedition. Instead, the ship’s mass detector discovers an enormous artificial object entering the Solar System. The opening sequence requires the player to identify the detected object, consult the included space chart for its range and angular coordinates, and direct the Starcross computer toward it. After completing the rendezvous and docking with one of the object’s airlocks, the player leaves the mining vessel and enters a vast alien artifact whose builders, purpose, and destination are initially unknown. The game is presented entirely through written descriptions. The player explores locations, examines the surroundings, collects and manipulates objects, operates machinery, and communicates with computers or alien beings by entering commands in English. The parser recognizes more complex instructions than a simple verb-and-noun system, including pronouns, prepositions, multiple objects, several commands on one line, and orders addressed to another character or machine. Progress can be saved and restored, while the SCORE command reports points, moves, and the player’s current rank. Most of the adventure takes place aboard a rotating cylindrical spacecraft whose inner surface produces artificial gravity. Its colored corridors and airlocks connect laboratories, repair facilities, computer rooms, cargo areas, alien habitats, and a central region containing vegetation and other constructed environments. Because the vessel’s orientation does not always correspond to ordinary terrestrial directions, mapping is useful for understanding how its rings, outer hull, central axis, and control structures connect. The artifact contains several alien species, some hostile and others potentially helpful. Progress requires observing their behavior, determining how to communicate or trade without a shared language, and deciding when confrontation can be avoided. Other dangers include malfunctioning machinery, unsuitable atmospheres, vacuum, weapons, damaged passageways, and events that occur after a particular number of turns. Careless actions can kill the player, destroy useful equipment, or make the adventure impossible to complete, encouraging experimentation alongside frequent saving. Many puzzles involve understanding unfamiliar technology rather than simply finding conventional keys. Colored crystal rods serve as portable control components that open airlocks, activate machinery, repair damaged systems, or reveal additional functions when placed in matching slots. The player must acquire the rods by exploring the vessel, assisting or outwitting its inhabitants, and solving problems involving light, gases, gravity, momentum, matter manipulation, transportation devices, and alien computers. Some puzzles permit alternate solutions or require objects obtained in distant parts of the ship. The broader objective is to uncover the artifact’s nature, restore its principal systems, collect the components needed to enter its central control structure, and demonstrate sufficient understanding to gain command of the vessel. Points are awarded for discoveries, successful interactions, recovered rods, repaired machinery, and progress toward controlling the ship, with a maximum score of 400. The Apple II, Atari 8-bit, PC Booter, and TRS-80 releases are among the original 1982 editions. Infocom’s Z-machine allowed the underlying adventure to be transferred between computers, so the principal differences between platforms concern screen layout, line width, fonts, keyboard handling, disk access, loading speed, printing, and save-game procedures. Different releases may also contain minor revision-level corrections, but no substantial platform-exclusive scenarios or gameplay features are documented. Starcross' parser and text-adventure structure build upon Infocom’s earlier Zork games and the tradition established by Colossal Cave Adventure. Its discovery and exploration of a mysterious rotating cylindrical spacecraft are particularly reminiscent of Arthur C. Clarke’s novel Rendezvous with Rama, while elements of its alien environments and hard-science-fiction puzzles also reflect the influence of Larry Niven’s Known Space stories.
