Every object is governed by orbital mechanics, from moons to ships to projectiles and scrap. You’ll learn to master the physics of space in the most approachable orbital mechanics game around.

Ship Customization

Outfit your ship with lasers, coilguns, particle beams and point defense systems inspired by real world weapons concepts. Craft new strategies with over 50 unique ship upgrade options.

Use Physics Creatively

Use space and physics to your advantage by making use of radiation, magnetic fields, atmospheric drag, and debris for defense or offense.

Heat Management

Balance your ship's fission reactor’s control rods, coolant and radiator panels to remove waste heat and optimize your ship’s systems.

In-depth Targeting and Sensors

Manipulate infrared heat signatures using deep sensor mechanics to track targets, get firing solutions and evade enemy targeting.
