The ArmorSim release date for Steam Early Access is 2026-09-16, as listed on the live Steam store page for AppID 5159810 at the time of writing on 2026-09-15. The planned Early Access duration is roughly twelve months, so the full 1.0 release is expected sometime after the EA window. Some third-party cached listings, including a G2A news spotlight, still show a 2026-09-07 date; treat that as a research-date discrepancy that the live Steam store supersedes.
When does ArmorSim release?
The ArmorSim release date is 2026-09-16, per the live Steam store sidebar for AppID 5159810. The store page is updated by the developer, Galimov Dynamics (publisher of record: Timerlan Galimov). Because Steam store pages can be re-saved in any timezone, a buyer should re-open the store page the moment they are ready to install. The Early Access window is a real paid release, not a soft launch. The store description describes a sandbox with fourteen armor materials, four penetrator cores, and three solver tiers (NORMAL, ADVANCED, ULTRA) that is intended to evolve over roughly twelve months. That EA duration is the developer's stated plan; it is not a hard release date for version 1.0.
What "Early Access" means for the ArmorSim launch
Early Access on Steam means the game is purchased at a discount relative to the planned 1.0 price and that the buyer accepts a build that is still in active development. For ArmorSim, the practical consequences are: solver behaviors may change, the materials list and penetrator roster may expand, and ULTRA mode may be limited in early EA. Buyers who want a feature-frozen build should wait until the EA banner is removed from the Steam store page; buyers who want to shape the roadmap should join the Discord and the Community Hub discussion boards listed on the store sidebar. The store description lists what is in the EA build right now: the scene editor, the three solvers, the documented material set, the three service-ammunition families, the four penetrator cores, and the slow-motion replay workflow that exports a replay file measured in megabytes.
Is the ArmorSim release date stable?
The 2026-09-16 date has been stable on the live Steam store page through the research window. No publisher announcement or Steam news post on the Community Hub has moved the date as of 2026-09-15. If the date shifts, the change will appear first on the Steam store sidebar, then on SteamDB's metadata snapshot for AppID 5159810, then on the developer's social channels linked from the sidebar. A cached G2A news spotlight still reports a 2026-09-07 Early Access start. That figure is a research-date discrepancy: the article was indexed before the developer finalized the live Steam date. Readers who only saw the G2A headline should ignore it and rely on the live store.
Where the launch date is announced first
The launch date for ArmorSim is announced first on the live Steam store page (store.steampowered.com/app/5159810/ArmorSim/). The change is then mirrored on SteamDB (steamdb.info/app/5159810/), the Steam Community Hub (steamcommunity.com/app/5159810), and the developer Galimov Dynamics social channels linked from the sidebar. The order matters: if you only check one place, the live store sidebar is the source of truth.
