The latest official public announcement for IRON NEST: Heavy Turret Simulator is IRON NEST - PATCH 1.0 (1577), published August 9, 2026. It fixes replay and turret-state reset problems, several crashes and memory issues, Blindfire spotter positioning, ultrawide stopwatch placement, and localization. It also removes the pause-menu Chromatic Aberration option. Update before following an older mission-reset, crash, or display workaround.
2950790. The public version label remains 1.0. The parenthetical numbers 1577, 1558, and 1547 are preserved from official post titles and are not described here as Steam BuildIDs. Demo 4300500, Playtest/Beta 4300490, and testing branches are outside the default timeline.Current public status
IRON NEST left prerelease status as a full 1.0 release on August 6, 2026. The Store lists native Windows support. Steam Deck has a separate official Verified announcement and runs through SteamOS/Proton; that does not imply a native Linux build.
PATCH 1.0 (1577) is the current official public patch at this check. A SteamDB cache, test-branch number, old Demo video, or local file timestamp cannot replace an official public announcement. When those sources disagree, use the public announcement for release status and reproduce gameplay claims on base-game AppID 2950790.
What PATCH 1.0 (1577) means for players
The most important change for walkthroughs is state reset. Official notes say mission events now reset on replay, and turret position and movement reset between missions. A replay that began with old triggers or a Nest origin inherited from the previous operation could invalidate otherwise correct route advice. Install the update, return through a normal menu transition, and start the replay cleanly before changing a save.
The patch fixes the mouse cursor after tabbing out and back in, improves diagnostics and handling for random crashes, addresses RAM and VRAM problems, and reduces log spam. Players troubleshooting those symptoms should update first, verify files, and then record any remaining reproducible sequence. The patch does not justify promising that every possible crash is fixed.
For mission presentation, Russian, Spanish, and Polish mission localization received fixes. Blindfire spotters that could appear off-centre were corrected. Ultrawide users gained a stopwatch horizontal-offset setting. The pause-menu Chromatic Aberration control was removed, so a guide should not direct current players to a toggle that no longer exists there.

2026-08-08 - IRON NEST - PATCH 1.0 (1558)
Type: Public base-game patch
The second post-launch patch fixes save-file corruption and failure to enter missions after a crash. It also fixes elevation and elevation-linkage state after leaving a mission following a shot, several cat carry or presentation problems, duplicated patron-name fragments, and engine-control lights. Mouse movement after loading and Discord account linking were improved, and a Motion Blur toggle for screen-shake events was added.
- The Discord code is an account-linking code, not a gift or redemption code.
- Players with crash-related mission-entry problems should update and verify files before altering a profile.
- Later 1577 reset and crash fixes supersede advice that stops at 1558.

2026-08-07 - IRON NEST - PATCH 1.0 (1547)

- Update before treating an old High Tide result as a hidden ending or alternate objective.
- Localized intelligence captured before this patch may not match current text.
- The official title does not introduce a new semantic version beyond 1.0.

Product and branch boundaries
June Demo notes and prerelease videos may explain development history, but they do not update a base-game 1.0 answer. A useful guide must name its product, patch scope, and platform when behavior could differ.
Roadmap items are not patch notes
The launch announcement names more content, missions, skirmish modes, features, music, eventual multiplayer, and a proper expansion as future work. The developer FAQ separately says multiplayer for the base game is planned, describes a longer-term standalone shared-platform co-op project, places consoles after PC, and places VR later. Workshop support is under consideration.
None of those statements proves a shipped feature or date. Keep multiplayer, co-op, console, VR, Workshop, and expansion status on the Multiplayer and roadmap page until an official public release changes the product. Do not create a DLC, server, or code page for an unassigned product.
How this timeline is maintained
For each official patch, record the exact title, publication date, AppID, public version label, platform scope, and source. Map each change to one canonical evergreen guide instead of duplicating workarounds throughout the site. A ballistics state fix belongs in ballistics, a replay correction belongs in the relevant mission, and a Cloud recovery change belongs in Saves and Cloud.
If a note says a symptom was improved rather than eliminated, the guide keeps a conservative recovery path. If the official title contains a number, preserve it without converting it to a semantic version or Steam BuildID. Community reports can reveal remaining cases, but only a current public-build reproduction should turn them into a player instruction.

Is IRON NEST still in Early Access?
No. The base game launched as full version 1.0 on 2026-08-06.
Is 1577 the Steam BuildID?
This page does not make that claim. It is the number in the official patch title. Public-branch status is taken from the official announcement, not inferred from the parenthetical number.
Did 1577 add multiplayer?
No. Multiplayer remains a future official plan; current 1.0 is single-player.
Did 1577 change mission routes?
It fixed replay event reset, turret position/movement reset, and Blindfire spotter positioning. Those fixes can change a broken pre-patch attempt, but the notes do not publish universal routes, grids, or shell counts.
Where are separate patch pages?
The canonical update history is this /updates/ page. It links affected evergreen guides so there are no thin, competing pages for every patch-title spelling.
