Picture a player floating outside their ship, tethered by a thin cable, drilling into an asteroid for rare minerals. Their oxygen meter is at 40 percent. They have two minutes of air left. The asteroid has exactly the mineral they need for the next engine upgrade. Do they keep drilling or head back? That decision is space survival.

Summer Engine helps you build that tension through conversation. Describe the space environment, the ship building system, the resource types, the threats: void exposure, meteor showers, power failures. The AI helps you create a game where every system that keeps the player alive is also a potential failure point.

Space survival is survival with extra stakes. The environment is instantly lethal without the right equipment. Every breath is a resource expenditure. The best space survival games make the player feel genuinely fragile and then give them the tools to overcome that fragility one upgrade at a time.

• Developers who want to build a Subnautica-in-space experience with base building and resource management.
• Designers with a strong alien world or procedural galaxy concept to hang a survival loop on.
• Teams building a sci-fi survival game with ship construction as the central progression system.
• Solo devs inspired by Subnautica, Empyrion, or Space Engineers who want to build their own version.

• Stranded on an Alien World

  Players crash-land on a hostile planet with no help coming. Build a base, gather alien materials, repair the ship or build a new one, and escape. Subnautica structure with space aesthetic.

• Space Station Construction

  Players build and expand a space station in orbit, managing power, oxygen, crew, and threats. The station is the base and the game world simultaneously.

• Asteroid Mining Survival

  Players fly between asteroids mining resources, upgrading their ship, and trying to survive increasingly hostile deep space sectors.
