A covert biological research facility is where it all began. A virus became airborne and resulted in deadly consequences.
Z.E.U.S (Zombie Enforcement Uprising Section) were sent to deal with the outbreak. However, in what was thought to be a successful mission, reports are coming in containing new Intelligence.
A Circus set in the city has reported strange behaviours in some of their staff. Some are also reported as missing. Intelligence received shows that some individuals were somehow led into the Outbreak Zone where the sound of screams, laughs and other sounds can be heard.
Accompanied by an elite team, Z.E.U.S must enter the Outbreak Zone and find out what exactly has happened. The order received is “Shoot to Kill”.
