Launch Window

Launch Window is a single-player physics-based automation game about building interplanetary supply chains governed by Newtonian orbital mechanics. You’ll transport resources and populations between colonies across a solar system, growing from a lone outpost into a fleet-driven civilization.

Begin on a barren moon; over years you evolve from a hand-picked handful of ships to hundreds of autonomous vessels, following trajectories you planned to link a sprawling, self-sustaining colony.

• Coordinate fleets of 1,000+ ships using Newtonian physics; automate orbital shipping lanes by plotting routes rather than issuing micro burns, letting the laws of motion handle thousands of trajectories in parallel.
• Build across entire spherical worlds, placing structures anywhere on a planet’s surface, then weave on-surface production into orbital logistics that connect distant colonies.
• Craft comprehensive logistical networks on-surface and between celestial bodies, delivering energy, ore, and people to where they’re most needed while balancing fuel, time, and risk.
• Research and unlock advanced tech, maneuvers, and buildings to improve throughput, resilience, and range, enabling you to tackle harsher worlds and longer routes.
• Launch Windows drive the pacing: only at specific moments can you reach destinations, so you must plan resource needs, transit times, and resupply cycles across multiple colonies to keep every route alive.
• Grow into a solar-system-wide network; deploy flagships to lead convoys, set up automatic routing, and let mass-produced ships handle navigation while you shape the big picture.
• All maneuvers on a single plane, so you can read hundreds of trajectories at a glance, maintaining clarity even when time warp accelerates to extreme speeds.
• Unique world resources per planet shape strategy: ice-rich moons for water/fuel, metal-rich rocks for factories, and outer planets offering rare resources with longer trips.
• Early Access with ongoing expansion; core mechanics are playable now, with terraforming, asteroid mining, celestial hazards, megastructures, and more ships and tech planned for future updates.

Launch Window is designed for optimization and consistency, enabling you to plan hundreds of trajectories and operate large fleets with extreme time warp—your ships keep their physics-consistent behavior and coordinated routes, even as the scale grows.

Created by a solo developer, Fred, Launch Window channels a love of sci‑fi, physics sims, and space into a game about vast logistics and satisfying orbital mechanics. Your feedback will help shape what comes next as the solar system expands.
