This is actually a non-continuity piece by the original Nemesis author and artist team of Pat Mills & Kevin O' Neill. It was done for the first issue of 2000AD's short lived roleplaying comic Diceman. In this game the objective was to make your way through the traveltube system to rescue Purity. Roll Them Bones!
If you made it through to the end of the game this is what you saw.
