Nimbos 4 was a place full of life… today thousands of cycles have passed since you walked alone on the surface of a dead and sealed world, with no possibility of escape.
However, a distress call from an illegal freighter can change your fate. Will you be able to cross 50 miles of radioactive hell swarming with killer Biodroids, clear the harbor of hostiles and board the freighter before it's too late to escape?


what is an MSX? 

MSX is a standardized home computer architecture, announced by Microsoft and ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, then vice-president at Microsoft and director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines.
