Play Solar Smash on Windows PC

Solar Smash on PC is a physics-based sandbox about shaping—and then disrupting—the cosmos. Rather than following a fixed campaign or pursuing a single victory condition, you take the role of a cosmic architect with control over planets, moons, weapons, and gravity. The game offers two connected ways to experiment: Planet Smash focuses on attacking celestial bodies, while Solar System Smash lets you arrange and simulate star systems. Across both modes, the appeal lies in choosing an intervention, watching its effects unfold, and deciding what to alter next. A planet can be a canvas to customize, a target for a spectacular weapon, or one body in a larger gravitational experiment.

In Planet Smash, select a planet or moon and try out more than 50 weapons and effects. The options range from lasers, meteors, nukes, antimatter missiles, railguns, and orbital ion cannons to UFOs, battleships, space fighters, black holes, supernovas, and giant monsters. Defensive tools such as shields and defensive satellites add another dimension to the destruction: the arsenal is not limited to attacks. You can test different choices against familiar solar systems or more exotic settings, including ring worlds and giant moons protected by planetary force fields. There is no stated requirement to use a particular weapon or complete a prescribed objective, so the practical loop is open-ended: choose a target, apply a tool, observe the damage, and experiment with a different approach. That makes the mode useful for players who enjoy comparing how very different cosmic forces affect a world, as well as those simply looking to cause dramatic destruction.

Solar System Smash shifts attention from individual targets to celestial mechanics. You can choose among three star systems, including our own Solar System, or create a system of your own with planets and set their orbits. From there, arrange collisions, introduce a black hole to disrupt orbital paths, and watch gravitational interactions reshape the system. The result is a sandbox for testing cause and effect: changing an orbit or adding a powerful object can alter what happens to the other bodies, and the simulation’s realistic gravity gives each experiment consequences beyond a single explosion. You can build a configuration, let it evolve, and revise your setup to explore another outcome. This system-making mode complements Planet Smash’s weapon-focused play, offering a broader scale of experimentation without turning either mode into a conventional management or strategy campaign.

On PC, a larger display helps make it easier to follow planets and moons across the scene, inspect an arrangement of orbits, and keep track of the full-scale effects of a collision or black hole. Keyboard-and-mouse input is also well suited to repeatedly selecting a celestial body, choosing among a large set of weapons, adjusting a system, and trying another action. Those advantages matter in both modes: Planet Smash encourages quick comparisons between tools, while Solar System Smash asks you to work carefully with bodies and their orbital relationships. The game describes its controls as intuitive, and its open-ended structure leaves room for both casual trials and more deliberate setups. Solar Smash contains flashing lights, which may make it unsuitable for people with photosensitive epilepsy or other photosensitive conditions; player discretion is advised.
