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.

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.

Where will you start?

Start with the scene editor, compare armor materials and configure ammunition for your first test.
