The world is in chaos after a virus escapes a secret zombie laboratory in Turret Defend Apocalypse. Everyone survives as best they can, and the chances are greater for those who managed to capture more resources and means that provide at least relative safety. You have a train with one platform, on which there is already a shooting turret. She will automatically fire at pursuing zombies. There are more and more of them, which means you need to add towers and improve them either by merging two identical ones or by purchasing improvements in Turret Defend Apocalypse.
