Nuclear Design Bureau Steam Page Facts, Specs and Store Details

Nuclear Design Bureau Steam details are worth collecting in one place, because this is a Windows-only Early Access release with a few hardware wrinkles that the store page states plainly. The app is 4190240, it costs $9.99, it is published by Design Bureau KB-11, and it uses WebGPU and Electron — which is why the requirements look unusually heavy for a 2D pixel-art sim and why the store explicitly warns that Linux, Proton and macOS are not yet supported.

The Store Page Facts

Everything below comes from the store page and Steam's own app-details API for app 4190240, so it is first-party information rather than tracker data.

• Steam Achievements are supported, and a global achievements page exists for the app.
• Steam Cloud is listed, so saves can sync with your account.
• Family Sharing is listed, so a shared library can play it.
• The store page discloses AI-assisted images, text and code used during development with developer review.
• The trailer on the store page is titled Early Access Trailer.

System Requirements and Hardware Notes

The specification is the part that surprises people, because the game is a 2D pixel-art design sim but asks for a modern discrete GPU with 8 GB of VRAM and a 16 GB memory floor. The reason is stated on the page: it runs on WebGPU and Electron, and requires up-to-date graphics drivers with WebGPU support.

Component	Minimum	Recommended
OS	Windows 10 64-bit, version 1903 or later	Windows 10 or 11 64-bit

Display	1280 x 720	1920 x 1080

• The minimum notes that integrated graphics are untested and that large designs run slowly on minimum hardware.
• A recommended-configuration note also lists a broadband connection, which fits an app built on web technologies.
• SteamDB's compatibility record lists the game as Unsupported on Steam Deck and SteamOS.
• The store page states plainly that Linux, Proton and macOS are not officially supported yet despite the WebGPU and Electron stack.

Features, Tags and Support Links

The feature set is modest but well matched to the genre, and the tag list is a good summary of what the game actually is. The page's own pitch is a hardcore sandbox engineering game simulating hydrodynamics, neutron transport and thermonuclear fusion, built around designing atomic devices to satisfy the demands of the State.

Feature listed	What it means for play
Save Anytime	You can save without reaching a checkpoint
Mouse Only Option	The design interface can be driven with a mouse alone
Playable without Timed Input	Nothing forces a reaction-time decision
Custom Volume Controls	Audio levels are adjustable per channel
Steam Cloud	Progress syncs through your account

The tag list includes Simulation, Strategy, Physics, Cold War, Science, Sandbox, Puzzle, 2D, Pixel Graphics, Dark, Difficult, Destruction, Programming, God Game, Historical, Tutorial, Atmospheric, Score Attack, Minimalist and Early Access — a fair description of a pixel-art engineering sandbox with a science theme. Support runs through the store page's own contact link, which points at the developer's Discord, alongside a published support email address. For what the game asks you to build with those tools, see the guide page; for hardware-related release context, see the release-date page.
