About Unknown Planet
Unknown Planet is an open-world survival adventure set on a randomly generated alien planet. After your spacecraft crash-lands, you wake with nothing and must gather materials, make tools, build a base and explore the planet while working toward a way to escape.
Explore the planet
Travel through biomes ranging from friendly grass fields to crimson forests, lava wastelands and bioluminescent areas full of lifeforms that want to eat you. Different biomes contain rarer resources for crafting more advanced items.
Build and progress
Build a base, grow farms and craft a light for nighttime. You can smelt metals, replenish supplies, make biofuel and batteries to power buildings, develop tools and equipment, and store resources. Defeating bosses advances you through the tech tree.
Survive and escape
Manage hunger and thirst by scavenging for food and water, cooking recipes, planting seeds and growing vegetable gardens. Defend yourself from fauna with increasingly advanced armor, melee and ranged weapons, and ammunition. Gather what you need to rebuild your spacecraft and find a way off the planet alive.
