Red Hope
A little greenhouse. A future worth growing.
Build a home on Mars. Keep your people alive when the sky turns against you, and remember their names when you can’t.
Red Hope is a single-player Mars colony management and survival game. Start with four pioneers, grow a settlement of glass domes, and balance power, air, food and the people doing the work. The next dust storm is already on the forecast.

Your colony. Your calls.
Five things the colony will ask of you before the first storm clears.
Give everyone a job
Set priorities for life support, gardening, repairs and construction. Pause to plan; resume to see your crew get to work.
Choose who comes
Each passenger request shows the four people asking to board: their line, their trait and who they came with. Take them as they are, or decline and wait for the next four. Book supplies, manage charter income, and decide whether a loan is worth its repayments.
Weather the storm
Prepare your reserves, get everyone inside and answer the storm’s questions: send someone out, or wait it out. Repair the damage when the sky clears.
Read the record
The expedition log keeps your colony’s story: arrivals, decisions, the shaken, the close calls and the lost, by name.
From the record
Three moments from the demo, as the colony saw them.

The full game is being built on the same colony: room to grow past 16, more to build and more to decide. There is no release date yet; we will say so when there is one.
