Killing Floor: Calamity is a top-down shooter created using assets from the original Killing Floor.

There is no actual Trader for these maps, instead a shop menu just appears between waves, regardless of where the player is.

In addition to selecting your map, you also select your Difficulty and Game Length. Though "Hell on Earth" difficulty is just called "Hell" and there is no "Suicidal" difficulty.

There are also Medals you can earn for each map.


Unlike other games, you can also set the map to Random, which has the description of:

Can't decide where your horrific death...sorry, we mean "historic destiny"...awaits? Let us do it for you.
