Armor Sandbox

Armor Sandbox is a 2D impact simulation/sandbox. Pick something to shoot, pick something to shoot at, and watch what actually happens.

Nothing here is a canned animation. Every plate, every projectile and every fragment is made of particles that carry real material properties: density, strength, melting point, heat capacity. Deformation, fracture, spalling, heat, fire and detonation all fall out of those numbers. Swap the steel for glass and it shatters instead of denting — because glass is brittle, not because somebody drew a shatter effect.

WHAT IS IN IT

• +80 materials: steels, aluminium alloys, tungsten, tantalum, ceramics and glass, concrete and stone, wood, rubber, water, fuel, explosives

• +60 projectiles: from pistol rounds to APFSDS long rods, shaped charges and hypervelocity rods

• +60 targets: plates, layered armour packages, deep blocks

• +15 vehicle cutaways: T-34-85, Tiger I, Panther, Sherman, IS-2, T-55, T-72 with and without reactive armour, M1A2, Leopard 2A6, Challenger 2, BMP-1, M113 and more, each with its real armour layout, ammunition, fuel and engine inside

• +40 ready-made experiments to start from

MAKE YOUR OWN

Paint projectiles and targets pixel by pixel, choosing the material of every pixel. Mirror, outline, replace, snap to a grid. Save them to your library, and send a design to a friend, or to your own PC, as a single small file.

IT RUNS ON A PHONE

The physics core is one flat block of memory and runs in a background thread, so the screen keeps up while the simulation works. Quality is measured against your device the first time you open the app, from 18,000 particles up to a million on a desktop.

NO ACCOUNT, NO ADS, NO TRACKING

The app makes no network requests of its own. Nothing you build leaves your device unless you export it yourself.
