## Groundfall Description
Groundfall is an educational nuclear blast simulator built on declassified physics models.

Place a detonation on a map and visualize blast zones, thermal radiation, fallout patterns, and estimated human impact. Groundfall is designed to help users understand the real-world consequences of nuclear weapons through clear simulations, historical context, and preparedness information.

WHAT YOU CAN DO

- Simulate nuclear weapon effects on any city or location
- Compare historical and modern weapon yields
- View blast, thermal, radiation, and fallout zones
- Explore real-world conflict scenarios
- Analyze fallout direction using wind data
- Review casualty and damage estimates
- Learn about nuclear physics, arsenals, history, and preparedness
- Save and export simulation results

FREE STARTER MODE

Groundfall is free to download and includes limited access so you can test the core simulator before upgrading.

EDUCATIONAL PURPOSE

Groundfall is not a game and does not promote violence. It is an educational tool for understanding the destructive effects of nuclear weapons and the importance of prevention, preparedness, and informed public awareness.
