The Game at a Glance
What is ArmorSim?
ArmorSim is an indie terminal-ballistics simulation sandbox developed by Timerlan Galimov and published by Galimov Dynamics. The simulator models projectile impacts against custom multi-layered armor arrays using published engineering equations and continuum physics rather than pre-baked damage animations or hit points.
In a typical test run, players construct target arrays from structural metals, ceramics, and reactive cassettes, select or customize kinetic or chemical ordnance, and fire. The engine calculates rod erosion, plugging, and residual velocity across analytic or continuum solvers, allowing orbit-camera inspection of deformation.

Download and System Requirements
Get ArmorSim on Steam and check the minimum PC requirements before installing. The listed requirements include 64-bit Windows 10, 8 GB RAM, a GTX 1050 or RX 560, and 4 GB of storage.
The simulator officially requires a 64-bit installation of Windows 10.
Systems require at least an Intel Core i5-4460 or AMD Ryzen 3 1200 processor.
Continuum physics calculations in Ultra mode are CPU-bound and scale with physical core counts.
More details
The base game installs in 4 GB, though detailed simulation replay files can consume substantial disk space.
Beginner Guide
Build a target, adjust its materials, thickness, angle and spacing, then select a projectile and fire. Review penetration results and slow-motion damage before changing your setup.
Insert a structural or armor plate object into the graphical 3D workspace.
Left-click directly on the placed plate in the viewport to unlock the right-hand inspection menu.
Use properties panel sliders to adjust plate thickness, spacing gaps, and impact angles.
More details
Choose a service round or custom projectile from the left menu and fire to resolve the impact.
Modes Guide
Compare Normal, Advanced and the limited Ultra solver preview by their outputs and simulation scope. Explore the separate 2D Playground, 2D Advanced and 3D menu groups introduced in version 4.0.0.
Delivers split-second analytic solutions using Alekseevskii-Tate rod erosion and Recht-Ipson velocity equations.
Tracks per-layer energy dissipation, wear fractions, and ballistic limits across spaced or composite arrays.
Calculates material deformation and physical craters over several minutes using an axisymmetric Lagrangian mesh.
More details
Provides real-time planar physics testing for large structures, shaped charges, and rapid firing iterations.
Armor Materials Guide
Explore reactive armor, backed ceramics and composite backing plates for layered targets. Material properties drive the simulation, with source labels distinguishing measured, derived, fitted and assumed values.
Materials include cast armor, Armox 500, mild steel, aluminum alloys, and titanium for structural plates.
Silicon carbide, boron carbide, and aluminum oxide serve as hard strike faces to shatter incoming penetrators.
Textolite, Kevlar, and fiberglass function as spall liners and intermediate support layers.
More details
Kontakt-1 cassettes and elastomeric NERA packs physically disrupt shaped-charge streams and kinetic rods.

Build a custom shaped charge from a charge, liner and fuze in the Projectile Components section. Attached components travel with a projectile, while standalone assemblies can function as mines or charges against walls.
Insert a high-explosive block or specialized shaped-charge cavity block into the workspace.
Mount a 42-degree, 60-degree, hemispherical copper liner, or EFP liner against the explosive cavity.
Install a contact fuze, igniter, or microsecond timer fuze to trigger the chemical detonation.
More details
Ensure components contact each other or a carrier body so they bind into a single flying munition.

Four interceptor types launch plates, fragment cones, explosively formed projectiles, or buckshot.
More details
Radio-frequency interference zones degrade the flight trajectories of incoming remote drones.
RadarSim Guide
Use RadarSim's tactical console to inspect contacts, predicted courses and target tracking. Import OBJ or STL models into the physical-map beta, where detection considers geometry, aspect, range and surface coating.
Position ground-based radar units across the tactical map to monitor air corridors.
Observe sweeps on the Plan Position Indicator and assign track identities to detected returns.
Maintain multiple consecutive sweeps to confirm flight trajectories and kinematic approach points.
More details
Launch guided missiles along simulated flight paths that track active radar updates to the target.
Electricity Guide
Connect device outputs to inputs with the wire tool to build circuits using batteries, switches, sensors and actuators. Fragments can sever wires, and damaged devices stop working.
Install electrical generators or batteries on the 2D canvas to supply circuit power.
Mount laser tripwires, proximity sensors, radar, thermal, acoustic, or impact devices.
Wire components together with conductive runs that can be physically severed by blast fragments.
More details
Link sensor logic gates to igniters, active protection launchers, or explosive countermeasures.
Quick Answers
Frequently Asked Questions
What platforms does ArmorSim support?
ArmorSim officially supports 64-bit Windows 10 systems on PC. There is no official native support for macOS or Linux.
How much does ArmorSim cost on Steam?
ArmorSim is available in Early Access on Steam at a regular price of $18.99 USD.
Does ArmorSim use hit points to determine penetration?
No, ArmorSim abandons hit-point pools and pre-baked animations. Damage and penetration outcomes are computed directly from published terminal-ballistics models and material physics.
Why does ArmorSim Ultra mode take so long to calculate?
Ultra mode runs a CPU-bound axisymmetric Lagrangian continuum solver that computes high-strain deformation and erosion cell by cell. Depending on physical processor core counts, each shot calculation can take several minutes.
Are Plane mode and RADARSIM free in ArmorSim?
Yes, both 2D Plane mode and RADARSIM were permanently unlocked for all base game owners in post-launch updates without extra DLC fees.
What are the minimum PC hardware requirements for ArmorSim?
The minimum specifications require 64-bit Windows 10, an Intel Core i5-4460 or AMD Ryzen 3 1200 processor, 8 GB of RAM, a DirectX 11 compatible GTX 1050 or RX 560 graphics card, and 4 GB of storage space.
