It is the year glork-too-vleep, or mid-20th century according to Earthling time. We recently stumbled across this planet called Earth and discovered intelligent, albeit primitive, life. The most intelligent and valuable of these specimens are the creatures known as cows. Many precious secrets of the universe have already been discovered through our studies of these cows, but to our frustration, we've found these particular Earthlings to be far too tranquil to harness for our political purposes.

Alas, for our galactic goals we must settle upon the second-most intelligent form of life on Earth: the human being. These creatures are just intelligent enough to meet our puppetary standards. Their brains appear eager to be molded, and their civilization perfect for our siloing, so we've selected a small municipality to begin our trial invasion.

Aliens have come to silo humans — brainwash, steer, and preserve human civilization — for their cosmic purposes! In SILOS (Secret InterLopers from Outer Space), players control competing factions of aliens who abduct and brainwash humans and cows while secretly invading their community. Players tussle for majority influence in the key locations of this small town as they seek to activate location powers and control human specimens for societal power.
