Cavern is a DLC map added in The Old City update.

Like all other DLC maps, it is available from the very beginning and doesn't need to be unlocked.

Description Edit

Cavern takes place down in the entrance of a huge cave with a lake on the bottom. Several platforms on different levels have been built here, which are connected by walkways, teleporters and jump pads.

There is only one single spawn point at the entrance of the cave, from which all land enemies always follow a single path to the core without any alternative routes. Air enemies do not spawn on this map.

The buildable area consists of several long and narrow paths between the individual teleporters. Most places don't offer more than two blocks of width, which makes it hard to build a complex maze here.

The level's narrowness forces a tough trade-off between coverage and maze length; if towers are placed to force mobs to travel in a zigzag, only a few towers will fit on each platform. If you have purchased the Killing Floor DLC, this is the level to go wild with it, as Killing Floors can easily turn every square of the maze into brutally damaging zones.


The following towers are available when playing Cavern in single player:

Single-player waves
