Nuclear Design Bureau description

Nuclear Design Bureau

NUCLEAR DESIGN BUREAU is a hardcore sandbox engineering game where you design and test nuclear devices. You are the Chief Engineer of a secret Soviet design bureau. The State issues a target and a warehouse full of dangerous materials. Some directives limit materials. Your task is simple: build a device that gets the job done. This is a prototype, not a finished game. Expect bugs, missing features, and big changes ahead.

How it works

  • Receive Directive: Read technical mission requirements and material constraints.
  • Design: Paint materials directly onto the blueprint grid; build your primary, casing, and supporting systems.
  • Simulate: Hit the red button, run full detonation physics in real time, and watch the blast in the Detonation Viewer.
  • Refine: If it fizzles, fails, or wastes material, iterate and improve.

Core features

  • Physics-driven Simulation: Real-time modeling of shockwaves, heat, radiation, and chain-reaction behavior.
  • Detonation Viewer: Observe detonations as they unfold with live visual feedback on blast behavior.
  • Campaign Directives: Structured mission progression with technical goals and constraints.
  • Sandbox Mode: Unlimited experimentation with full design freedom.
  • Iterative Engineering Loop: Build, test, diagnose, and optimize.

Early Access

The current Early Access build is fully playable and includes the core loop: Design → Simulate → Refine; Sandbox mode; Campaign directives; and save/load systems with ongoing stability improvements.

This is ongoing development. Expect balance changes, physics upgrades, and campaign iteration as we move toward a fuller release.

Roadmap highlights

  • More realistic detonation viewer with enhanced shockwaves, 3D-style presentation, and modeling of damage radii and thermal effects.
  • Smaller grid mode for higher realism; improved compression and levitated-pit physics.
  • Fission boosting with D-T gas; expanded materials and behaviors.
  • Campaign expansion around updated grid, physics, and destruction systems; more directives and missions; voiced campaign.
  • Additional bomb concepts (high-radiation designs, clean bombs, neutron bombs) and more presentation/audio tracks; public leaderboard.

Development approach

Early Access is where this game takes shape in public. Player feedback guides balancing, campaign pacing, clarity, and polish as we move toward full release.

The atom is not a soldier, Comrade. It is a force of nature. We merely tell it where to go.
