Advanced Star Trek

Advanced Star Trek is a Star Trek variant written for the IBM 370/158 in PL/I. The player controls the enterprise and will encounter Klingons, Romulans and Tholians. Klingons have two different ship types, Romulans are invisible and can follow the player unnoticed. Tholians attack in groups of three and have a web-like tractor beam. Another ship, the Fairy Queen is also available in emergencies.

The player goes hunting for enemies in a galaxy made up out of 10x10 quadrants which are again divided up into 10x10 sectors. The player can also travel through time, but this can have some serious consequences.
