About
Your homeworld has run out of resources. As an engineer, you land on an untouched planet with a single task: build a factory that runs by itself, and construct the rocket that can save your home.
But you are not alone. Nearby, the young colony of Weitmark is struggling to survive and asks for help. Send it supply capsules and watch a few huts grow into a town. In the end, the rocket can fly to only one destination. Who will you help?
AUTOMATE
• Drills, smelters, formers, joiners and synthesizers chain into long production lines, from the first ore to rocket segments
• Conveyors, pipes for water and oil, tunnels and splitters: drag your lines with a finger
• Drones carry cargo across rivers, lava and crevasses to distant deposits
• Every machine has a throttle, and boost modules push it even further
POWER
• Wind, sun, geothermal, coal, oil and nuclear
• Day and night, with batteries as a buffer: when power runs short, the factory slows down instead of stopping
FOUR WORLDS
• Grassland, Volcanic Land, Ice World and Desert share the same resources, but each has its own bottleneck: a river, lava flows, crevasses or scarce water
• Salvage wrecks for data cores that unlock research and alternate recipes
MADE FOR MOBILE
• Your factory keeps working while you are away, and a summary shows what came in
• Built for touch in landscape, on iPhone and iPad
• Detailed pixel art and painted story scenes
• Achievements across all your games
• Progress saved via iCloud
• Playable in 9 languages
