There are three WADs in the series; each one takes place in a large, dark forest, with one or more "ghouls" inside. The "ghouls" are fast-moving, usually instantly-killing monsters with a disturbing appearance. The point of each WAD is to kill the ghouls before they kill the player.
The WADs are considered to be some of the scariest ever made, evoking feelings of terror. The author constantly reminds players that the wads are not for the faint of heart.
Ghouls vs Humans
Another mod by CutmanMike is Ghouls vs Humans, which brings the Ghoul cast into the deathmatch arena. Rather than a horror wad it is a class based team deathmatch mod for use with Skulltag, and is one of the first mods to use TEAMINFO to set playerclasses to certain teams (For example human team and Ghoul team). Each class has unique abilities, advantages and disadvantages.
