ABOUT THE GAME

Connecting electricity and food,
Move colonies on a monthly basis.

``Terra Infirma: Colony'' is a turn-based colony simulation by joinfive. Manage power, minerals, food, population, and funds on a monthly basis, and aim to make your outpost self-sustaining and buy its freedom from the Empire in 10 years.

01

Assemble monthly operations based on power generation amount

Uranium is sent to a generator to secure kW, which is then allocated to construction, mining, and production. At the top and right side of the screen, you can check the status of your funds, power generation, buildings, warehouses, and crew at once.

02

Search for unknown deposits on an expedition

Select colonists and scientists, time period, and targets of exploration and send out an expedition. The official explanation states that while you can explore and discover new deposits, expeditions also come with risks.

03

Connect buildings, production, and trade to a 10-year plan

Increase your workforce with houses, produce machinery with factories, and expand trade opportunities with landing fields. We will have 120 million XRP in stock by 120 months, avoiding food shortages and long-term deficits.
