Crux 92 is an action game for the ZX Spectrum developed by Marek Trefny and published by Ultrasoft in 1992.
The task of its crew is to find deposits of Filium (the main material of the 23rd century) in Crux constellation.
Spaceships can at these times replenish fuel and food on bases that were built on little planets.
Problem is that when IKERI needs to replenish its resources, the crew finds out that the base they need to land on is led by a main robot who revolted against humans and built a huge complex with 60 floors.
The player controls a cosmonaut whose goal is to destroy all enemies in the level and activate bombs.
