Navigate the complex challenges of Protocol Meltdown, where you must balance production and profit while keeping a volatile nuclear reactor from causing catastrophic failure.
About this game
A reactor simulation game, where you play as a new reactor operator, tasked with keeping "Project Vermillion," the new highly-unstable prototype reactor from BioFission Research safe.
Manage critical systems, like pressure, temperature, power output, feedwater levels, and most importantly, profit. Defend the reactor from mindless killing zombies we call "experiments," soulless saboteurs hired by big oil, and the tactical law-enforcement agents who found out too much about what happens inside the facility.
Play one of the four tuned difficulties alone, or bring some friends along for a more challenging experience with up to four players. Explore and manage the simulation, manage your funds, and keep the reactor stable for long enough to beat high scores, before the inevitable happens.
