Cosmic Castaway
Steam
You are the galaxy’s unluckiest starship captain. Crash-land on strange planets, gather scarce resources, and rescue your stranded crew. Each successful evacuation earns you stars — collect enough and you’ll unlock new worlds to explore.
Your crash-landings won’t curb your thirst for adventure. Build thriving colonies to shelter your crew, repair your ship, and defend against the hostile lifeforms of alien worlds.

Think fast. Food is a must if we want to survive and we are running against the clock. Buildings and objects are all crafted from the 4 key resources; Lumber, Stone, Food, & Ore. How those resources are utilized will play a key role in your eventual success or demise.
You will also have to manage an electric grid system to power non manned defenses and objects.

Sawmills, mines, fishing docks, farms, windmills, boardings, bridges, defense turrets, and more. Strategically placed resource infrastructure will yield results longer. Improperly placed/manned defenses could see the collapse of your colony.
Space engineers don’t have much training in battle. Luckily for you, your robot sentry drone is up to the task! However, as the colony grows, you will require more advanced defense systems. Strategically place these defensive systems to protect what you built and to advance further in your quest to rebuild your starship and blast off to safety.
From wreckage to refuge. With your crew, forge the way home.
