Werewolves are enemies in the Death Will Come mod. They use a melee attack. Sometimes they drop a Fang.

Grim Reaper's Encyclopedia Entry
They're lunartics.

Trivia
The word "lunartic" in their GRE entry is a portmanteau of "lunar" and "lunatic".

The "W" in the label for the forums for this mod appears to represent the Werewolf because it is furry and has sharp fangs.
