Complete interface localization for 12 languages, plus localization, stability, and device compatibility improvements. All five weapons remain free.
Aim meteors and orbital lasers at Earth in a replayable physics sandbox.
Turn a realistic Earth into a satisfying destruction sandbox. Unwind with spectacular, escalating damage: pick a weapon, choose a target, and watch impacts, heat, fractures, and molten scars permanently reshape the planet. Five weapons, five ways to cause a cataclysm: • Meteor Impact — tear through the atmosphere and strike the surface • Orbital Laser — press, hold, and drag to carve a burning path • Corebreaker Missile — launch, dive, and trigger a deep planetary blast • Thermonuclear Strike — unleash a huge fireball, mushroom cloud, and layered shockwaves • Orbital Cluster Strike — split near the target and bombard a wide area Rotate and zoom Earth to inspect persistent craters, burn zones, and fractures from every angle. Repeated attacks deepen the damage in the same region; reset the planet whenever you want a clean experiment. Version 1.1 opens all five included weapons with no ads, subscription, account, or required purchase. Core experiments work offline. Planet Cataclysm Lab is an entertainment-focused, simplified physics visualization. It is not a scientific, safety, or disaster-prediction tool.
