Black Cholera turned the cities into zombies. Defend the camp, find the cure!

The Black Cholera has swallowed the Morvan Basin: four cities overrun by hordes, and all you have is a walled quarantine camp. Each month the horde storms the gates: place your soldiers on towers and walls and command the defense yourself. Crack the four-compound formula in the lab, send scientists to the cities by convoy and deliver the doses safely. Starts October 31, free for everyone!
