Protocol Meltdown

Protocol Meltdown is a reactor simulation game in which you play as a new operator responsible for keeping Project Vermillion, a highly unstable prototype reactor from BioFission Research, safe.

Operate the reactor

Manage pressure, temperature, power output and feedwater levels, while also keeping an eye on profit. Explore and manage the facility, handle its funds and keep the reactor stable long enough to beat high scores before the inevitable happens.

Defend the facility

You face mindless killing zombies known as “experiments,” saboteurs hired by big oil, and tactical law-enforcement agents who have discovered too much about what happens inside the facility.

Solo and co-op play

Play alone across four tuned difficulty levels, or bring friends along for a more challenging experience with up to four players.
