The protagonist of this game is a maintenance engineer aboard I.S.T. Rident, a
space-faring passenger liner in the delta quadrant. Suddenly, two war ships
attack Rident. As the captain orders the passengers to escape on life boats,
the hero is knocked unconscious. Some time later, he finds himself in a
deserted spacecraft, and must find a way to escape from there, find out who
was responsible for the attack on Rident, and what has happened to its
passengers.

_Symbiocom_ is a first-person perspective adventure game, in which locations
are represented by pre-rendered backgrounds; camera can be rotated, but
movement is restricted to “jumps” between still screens, sometimes displayed
as short “on rails” sequences. The emphasis of the gameplay is on solving
puzzles, inventory- as well as logic-based. There are no characters to
interact with, with the exception of a few robots and the so-called
“symplant”, a symbiotic artificial intelligence implanted in the protagonist’s
brain.
