About this game

Meltdown Crew is an online co-op game where you have to control a 1980s style nuclear reactor by using proximity voice chat and phones to communicate with your friends. You and up to 5 friends have to prevent a total meltdown while producing as much power as possible.

WATCH OUT!

All objects are physics based, and fuel rods are fragile, bump into a doorway or a coworker too hard, and you’re both gone.

MONITOR THE SITUATION

The reactor is under constant change, cooling needs to be adjusted, fuel rods need to be replaced and thrown out, power will cut off and fuses will blow. But keep your cool in the control room and everything will be okay (probably).

COMMUNICATION IS KEY

The only way to keep the reactor stable is to work together. If you are in the control room, you can’t take action in time, so grab a phone and connect with your friends running around in the reactor.

IMPROVE AND UPGRADE

Upgrade your reactor with improved fuel rods, or new equipment.
