"Threshold Zero": High-Fidelity Nuclear Simulation

The Concept: "Threshold Zero" (Made for Steam)
This is a high-fidelity, physics-driven nuclear catastrophe simulator designed specifically for the Steam audience. It’s built for players who love technical sandboxes like Teardown, Universe Sandbox, or BeamNG.drive, where the "fun" comes from pushing a physics engine to its absolute limit.
The "Elevator Pitch"
Threshold Zero is a digital laboratory of destruction. It isn't a game about war; it’s a game about the physics of the impossible. You are given the keys to a hyper-realistic simulation where you can detonate nuclear devices across detailed environments and observe the consequences through a scientific lens.
The Core Pillars (Steam-Focused)
• True Simulation vs. Arcade FX: Every detonation is a real-time calculation of fluid dynamics and thermal radiation. The fireball isn't just an animation—it’s a volumetric entity that grows and reacts to the atmosphere.
• The "Shatter" Engine: Designed for PC hardware, the game features a material-based destruction system. Buildings don't just "disappear"; they are shredded by overpressure, with glass, steel, and concrete reacting according to their real-world physical properties.
• The Observer Suite: A deep set of "God-mode" tools designed for high-end PCs. Use high-speed Phantom cameras to watch the first micro-second of plasma expansion, or switch to thermal and radiation overlays to see the invisible killers.
• Steam Ecosystem Integration: Built from the ground up to support the Steam Workshop, allowing players to upload custom cities, real-world terrain, or experimental bomb designs for the community to test.
• Cinematic Sandbox: A dedicated "Photo Mode" and "Replay Editor" allow players to capture 4K, ray-traced footage of the apocalypse to share on the Steam Community Hub.
