Armor Sandbox App

Armor Sandbox App is a 2D collision physics sandbox. Choose what to launch, select your target, and see what actually happens. There are no pre-made animations here. Every armor plate, every round, every fragment, is made of particles with real material properties: density, strength, toughness, melting point, specific heat capacity. Deformation, fracture, spalling, high temperatures, flames, and detonation all stem from these figures. Replace the steel with glass, and it will shatter instead of dented, because the glass itself is brittle, instead of someone drawing a shattering effect. Game content more than 110 materials: all kinds of steel, aluminum alloy, tungsten, uranium, ceramics and glass, concrete and stone, wood, rubber, water, fuel oil, explosives, nuclear materials, and electrical components that can be energized 70 kinds of ammunition: pistol shells and rifle shells, tail stable shell piercing shells, shaped charge, broken armor shells, electromagnetic gun projectiles, and more than 90 targets of three missiles with rich details: armor plate, multi-layer armor, thick block, ballistic gelatin, bunker and circuit • 36 cross-sectional vehicles: T-34-85, tiger, leopard, Sherman, IS-2, T-55, M103, T-72 with and without explosive reactive armor, M1A2 Abrams, Leopard 2A6, Challenger 2, BMP-1, M113, etc., as well as cars, trucks, buses, tractors, fighter planes and helicopter gunships, each vehicle has real armor, ammunition, fuel and engines. More than 60 ready-made experiments, from a ricochet to a series of nuclear devices. Build your own works. Draw ammunition and targets pixel by pixel, selecting materials for each pixel. Supports mirroring, outlining, replacing, and grid snapping. Save it to your library, then share the design as a small file with friends or the community workshop. Adjust the material to change the strength, density, temperature or explosive power of any material, and every time the simulation will run according to your number. Connect the battery, capacitor, switch, sensor, timer, and detonator in the circuit. The current only follows the path you draw: insulated wires laid along the steel plate will not electrify the steel plate, while bare copper wires will electrify the whole plate. Pressure plates, trip wires, magnetic and proximity sensors, photocells, radio receivers, and high-voltage sparks that can break through the air. Hearing it, recording its impact, explosions, flames and flying ammunition, will all make sounds according to material and speed. Record your shooting as a video and share it. The physics core runs on the phone in a separate thread, so the simulation remains smooth even during runtime. The picture quality will be adjusted according to your equipment, from 18,000 particles to 1 million. No account required, no ads, and no tracking—unless you export your data yourself; anything you create stays on your device. It’s free, and watching it in its entirety is also free. Every built-in experiment can run completely, including explosives, nuclear devices and circuits, as well as every vehicle and material used in the experiment. Importing designs sent by others is also free. The full version is for creation: draw with high-energy, nuclear and electrical materials, edit the properties of each material, the library is not limited to five pieces of each category, export your design, and "extreme" and "highest" image quality. One-time purchase, no subscription required; both versions are ad-free. Supports Simplified Chinese, English, Portuguese, Russian, and Spanish. Originally named Armor Simulation. Shoot anything with anything. Realistic collision physics, not pre-rendered animations. Updated on October 21, 2026; available for Android and Windows emulators.
