UMBRA: A Solo Game of Final Frontiers is a map drawing game that puts you in control of a sci-fi colony as you struggle against starvation, the void, and the many threats that will assail you from above and below. This 48 page zine has everything you need to generate natural formations, alien ruins, enemies, technologies, and forgotten terrors. It has a simple turn-based combat system, rules for building your colony and optional challenges for a harder experience.
Inspired by games like Rimworld and Dwarf Fortress, UMBRA aims to capture the feeling of building and protecting a colony on an unforgiving alien planet.
All you to play is, a pencil, paper (preferably 1" grid), and a deck of playing cards.
