Armor Sandbox is a 2D physics sandbox and ballistics simulator. Pick something to shoot, pick something to shoot at, and watch what actually happens: armor penetration, ricochets, spalling, fire and explosions, all from real physics.
Nothing here is a canned animation. Every armor plate, every projectile and every fragment is made of particles that carry real material properties: density, strength, toughness, melting point, heat capacity. Deformation, fracture, spalling, heat, fire and detonation all come from those numbers. Swap the steel for glass and it shatters instead of denting, because glass is brittle, not because somebody drew a shatter effect.
TANK ARMOR PENETRATION
Fire an APFSDS dart at a Leopard 2, a HEAT round at a T-72 with reactive armor, or a rifle bullet at a steel plate, and the ballistics decide the result: how deep it goes, whether it ricochets, and what the spall does inside the tank.
WHAT IS IN IT
• 110+ materials: steels, aluminium alloys, tungsten, uranium, ceramics and glass, concrete and stone, wood, rubber, water, fuel, explosives, nuclear materials and working electrical parts
• 70 projectiles: pistol and rifle bullets, APFSDS long rods, shaped charges, HESH, railgun slugs and three detailed missiles
• 90+ targets: armor plates, layered armor, deep blocks, ballistic gelatin, bunkers and circuits
• 36 tank and vehicle cutaways: T-34-85, Tiger I, Panther, Sherman, IS-2, T-55, M103, T-72 with and without reactive armor, M1A2 Abrams, Leopard 2A6, Challenger 2, BMP-1, M113 and more, plus cars, trucks, a bus, a tractor, a fighter jet and attack helicopters, each with its real armor, ammunition, fuel and engine inside
• 60+ ready-made experiments, from a ricochet to a chain of nuclear explosions
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 share a design with a friend, or with the community Workshop, as a single small file.
TUNE THE MATERIALS
Change how strong, dense, hot or explosive any material is, and every simulation follows your numbers.
WIRE IT UP
Batteries, capacitors, switches, sensors, delay lines, detonators. Current goes only where you drew a path. Pressure plates, tripwires, magnetic and proximity sensors, photocells, radio receivers and high-voltage sparks that jump the air.
HEAR IT, RECORD IT
Impacts, explosions, fire and projectiles flying past all sound like the material and the speed. Record your shots as video and share them.
IT RUNS ON A PHONE
The physics engine runs in a background thread, from 18,000 particles up to a million, depending on your device.
NO ACCOUNT, NO TRACKING
Nothing you build leaves your device unless you export it yourself. Where Google Play cannot sell the full version (Russia), creator mode can be unlocked for a while with optional rewarded videos instead; everywhere else, and in the full version, there are no ads.
FREE, AND FULL
Watching is free. Every built-in experiment runs in full, explosives, nuclear devices and circuits included, and so does every vehicle and every material a preset uses. Importing a design someone sent you is free too.
The full version is for making things: painting with energetic, nuclear and electrical materials, editing the properties of every material, a library without the five-per-kind limit, exporting your designs, and the Extreme and Maximum quality levels. One payment, no subscription, and the full version never shows ads.
If you like ballistics, tank armor and destruction physics, this is your sandbox.
