Resistance is futile
In SILOS (Secret InterLopers from Outer Space), you will reposition your alien figures across key town locations to compete for majority influence. Activate an event card that benefits the players with the most influence. Abduct cows and humans, brainwash Earthlings, and trigger location powers in this thrilling race for societal power!








Why You'll Love It
A Brilliant and Dynamic Area Majority Competition
SILOS has players competing for influence across seven unique locations with three compelling incentives: abductions, mind control, and location abilities. Your vital decisions are driven by the powerful card effects and clear probabilities. The table elegantly displays which cards have and haven’t been revealed from the Common Deck, and which Faction Cards are still available, allowing players to weigh the risks and opportunities before them. This tactical harmony of positioning your figures and activating a card creates a dynamic nail-biting experience for the entire table.
The seven standard location powers and seven alternate location tiles allow you to explore a wide variety of setups and tailor the game to your group’s preferences. Thanks to this modular flexibility, SILOS feels endlessly exciting and fresh. Add in the crop circles module and permanent skill tiles from the Crop Circles expansion, and you’ll have a hearty strategic stew that you can endlessly feast on.

Another Layer to the Fun
