Overview
Protocol Meltdown plunges players into the high-stakes role of a reactor operator tasked with maintaining the stability of "Project Vermillion," a dangerously volatile prototype reactor developed by BioFission Research. This unique simulation blends intense resource management with thrilling combat scenarios. Players must meticulously oversee critical systems, including pressure, temperature, power output, and feedwater levels, all while keeping a watchful eye on the bottom line – profit. The facility isn't just threatened by technical malfunctions; it's under siege from relentless "experiments" – mindless zombies – as well as saboteurs hired by rival corporations and tactical law enforcement who have uncovered the facility's secrets.

- Multi-faceted Threats: Defend your reactor against hordes of "experiments" (zombies), corporate saboteurs, and tactical law enforcement.
- Co-op or Solo Play: Experience the chaos alone or team up with up to three friends for a challenging cooperative experience across four distinct difficulty settings.
