⚡ Welcome to Energy Technology Development Facility! Step into a massive research and testing facility where your choices shape the experience. Work with the facility to keep operations running smoothly, or go against it and create complete chaos. 🚀 Launch and test experimental rockets and nuclear devices, defend the facility from threats, explore a detailed environment, roleplay with friends, complete objectives, or simply discover everything the facility has to offer. Will you protect the facility, sabotage its operations, or become the reason for its next disaster? The choice is yours. 🖥️ Private Servers are FREE! ⚠️ The game is currently in active beta. Features, systems, and gameplay are still being developed and may change over time. Bugs and issues may occur. ⭐ Current Version: 0.21a 🔥 Inspired by Ryanblaze's Nuclear Blast Testing Facility and others.

Monetization — game passes
Game passes for sale and their prices, measured from the Roblox passes API. Developer products bought inside the game aren’t publicly listable.
Badge funnel
How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.
