Rumble At The Graveyard of Robots - A Post Apocalyptic Mars Stars Without Number Actual Play Adventure

The party narrowly escaped being eaten by a shoggoth the size of a small bus and a bunch of mutant cannibal red men. The party detonated small atomics to escape the ancient Lovecraftian horrors.
The salvagers they were with made a brand new tunnel into the Mar rock with atomic drilling machines to escape the horrors of ancient Mars past.
The party was led deeper into a very alien set of ruins that sat square below the teeming serpent's lair. This ancient hate filled tomb of old was the sight of many ancient battles where an entire alien city had been laid waste by entropic weaponry. The whole place was a mass of buildings that looked grown rather then build.
There were layer after layer of ancient bio mechanical buildings built by the fabled Mountain Kings of old Mars. These ancient aliens used both cybernetic horrors and slaves of red men to do their bidding.
They were hundreds of years extinct but their creations were still there silently guarding the hoard of ancient relics and technology.
The PC's accidentally activated a war bot and had to fight the thing till complete deactivation.Around them were the hulks and shells of a billion robots and robotoids surrounded by fields of skeletons of red men.
They are still exploring this tomb of cybernetic horror.
Some of the nasty encounters still waiting for them are as follows.
