Labyrinth of the LIZARDROIDS (2010)

From publisher blurb:

The Mars Challenge offered a tremendous prize to the corporation best able to develop a system to explore and colonize Mars, and Wolcott Industries had the best and most brilliant idea.

Create Artificial Intelligences based off the lizard brain - natural desert survivors! Give them mostly humanoid bodies so they could prepare a human colony, make them tough enough to survive the trip to Mars and the brutal, rugged exploration of its surface, give them the ability to carve through rock, smelt metal, and produce the machines that mankind would need, and you have a force capable of making the red planet our home before we even step foot on it!

Pity they accidentaly got turned on while they were on Earth... just outside your home city.

Explore the complex carved under your city before it collapses under the weight of the buildings in a catastrophe of bibilical proportions! Meet and fight ten different varieties of Lizardroid, each more dangerous than the last! And meet the enigmatic Solomon Wolcott - brilliant industrialist and cold-blooded murderer!

Someone does need to fix these little problems, from time to time... that's why thereare Player Characters!
