Steam Deck Verified status
IRON NEST: Heavy Turret Simulator is marked Steam Deck Verified on its Steam listing. Verified is Valve’s strongest compatibility category and indicates that the reviewed game experience met the Deck program’s requirements at the time of testing. Players do not need to treat the game as merely an unsupported Windows experiment on the handheld.
The rating sits alongside full controller support on the store page. That pairing is important for a game built around walking between machinery and manipulating controls. It indicates that a controller-driven path is part of the supported Steam presentation.
Compatibility badges can be reevaluated after game or platform updates. Check the current store badge before buying specifically for Deck. This guide records the status verified on August 7, 2026 rather than promising it can never change.
Steam Deck questions
Does Verified mean native SteamOS code?
No. Valve can mark a Windows game Verified when it works through the Deck’s compatibility environment. The developer separately states that a native Linux build is not planned.
Is a keyboard required?
Steam lists full controller support, so the official store does not require a keyboard-only workflow. Exact typing, notebook, or remapping behavior should be checked in the current build. Community layouts are optional rather than proof of missing official input.
Can I expect a fixed 30 FPS?
No Deck-specific fixed frame-rate guarantee is published. The 30 FPS figure belongs to the minimum PC target at 720p low. Deck Verified addresses overall compatibility, while actual performance can vary with settings and updates.
Does Steam Cloud mean console cross-save?
No. Steam Cloud covers the Steam environment and does not confirm a future-console transfer system. Console platforms, accounts, and release details have not yet been announced individually.
Controls on Steam Deck
The main listing says full controller support, but the supplied sources do not provide an official button-by-button Deck layout. Exact bindings, gyro use, trackpad behavior, interface scaling options, and recommended community layouts should be checked in Steam Input and the current game settings. This page will not invent controls.
The operator loop includes moving in first person, reading teleprinters, working with the tactical map and calculator, choosing ammunition, and manipulating loading and aiming mechanisms. A verified controller experience means those tasks can be reached on Deck. It does not imply that every player will prefer the same sensitivity or input method.
If an external controller is connected, Steam Input settings may affect which layout appears. Keep the official layout available before experimenting with community mappings. When troubleshooting, first restore the default configuration so an unsupported remap is not mistaken for a game defect.
Performance expectations
Steam Deck Verified does not publish one guaranteed IRON NEST frame rate in the checked source. The general minimum PC target is an average of 30 FPS at 720p on low settings. That number gives context but is not a Deck-specific benchmark.
The demo received lower-specification optimizations before the full release, including work on degradation during extended sessions. The free demo is therefore the best no-cost way to see how the current build behaves on your own Deck and settings. Test a complete mission rather than only the first few minutes.
Power limits, refresh-rate caps, operating-system versions, Proton updates, game patches, heat, and background downloads can affect results. Avoid claiming a fixed battery duration or frame rate without a repeatable current measurement. No official battery-life figure is published for this game.
Steam Deck is not native Linux support
Steam Deck runs SteamOS, but the developer does not plan a native Linux build at this stage. The Windows version instead operates through the compatibility environment used by the Deck. Valve’s Verified result and the developer’s lack of native Linux support are not contradictory.
The developer also reported that the game appeared to work on desktop Linux through Proton 10.0. That statement is useful evidence, but official support remains limited because the two-person team cannot maintain a native version. Desktop distributions, drivers, and hardware create a wider range of combinations than the standardized Deck.
Deck owners can use the Verified badge as the specific platform signal. Desktop Linux users should read the separate Proton status and be prepared to consult current community reports. Neither group should download unofficial modified executables.
Before playing on Deck
Confirm that you are installing the released main app, ID 2950790, or the official free demo, ID 4300500. The development Playtest app has a different purpose. Keeping those entries separate prevents old test data from being mistaken for the retail Deck build.
Allow more free space than the listed 5 GB minimum so updates and caches have room. Start with the game and Steam Input defaults, then adjust display and performance controls gradually. If text or a station is difficult to operate, record the exact build and setting before reporting it.
Cloud support is listed on Steam, but this guide does not promise cross-store or future console save transfer. Family Sharing is also listed, subject to Steam’s account and eligibility rules. Console and VR versions remain future plans with no confirmed relationship to the Deck license.
Deck status: Verified. Controller listing: Full controller support. Exact frame rate and battery duration: not officially specified.
