"Survivors followed a radio broadcast sent from this subway station and they are hoping to find some shelter and supplies here. It looks like the place is overrun though, there seems to be nobody around, except the survivors who just arrived here by train. Still, it sounds like there's somebody or something lurking around.. You should check out what's going on here."
— Official description

Underground is a Survival map featured in Zombie Panic: Source.


Underground is a medium-large survival map set in an underground subway system below the streets of a likely abandoned city. The map primarily consists of long hallways connecting platforms to other areas, such as the restaurant, security room, basement, etc. The human team spawns on the platform by the train they arrived in, while zombies spawn in the depths of the tunnel systems and corridors.

  • There are many places that are easy to defend on this map with alternate exits. If desperate, camping is a tactic which can help you lay low while trying to survive.
  • Stay away from the hallways with the warning signs posted on them of infection, as zombies tend to spawn in these areas.
  • It is recommended to travel with a group if you are a new time player on this map, since many areas look the same it is incredibly easy to get lost.
