Four Mighty Golems stand against one billion screaming Robo-Bugs. Good odds! But every shot drains your life, and with only one Heartstone left, you're going to have to learn to watch each other's backs... and keep one hand on the Heartstone! Stone-Cold Co-Op has never been so hard! This intense team-work survival experience requires players to work together against the hordes of RoboBugs that won't rest until the last stone golem is pounded into rubble. Carry a Heartstone with you or cover your friends as they lug it along, and grab it for an energy boost when you can because each blast of your weapon drains a little of the juice that keeps you going. With no safehouse to run to and no place to hide, nobody can go it alone in this fight.
