Ettin

From Doom Wiki

The player is being mobbed by Ettins on the Dark Crucible in Hexen

Ettins are monsters from the game Hexen. They are two-headed monsters outfitted with armor and maces, but are nonetheless straightforward to kill, even with 175 Hit points. Ettins are also the most common enemy in the game, and the first encountered. In addition, they spawn randomly (about one per minute?) as long as the player is on a given map. Their melee attacks consist of mace swings; however, these only cause a small amount of damage and are easily avoidable by the player. They gib when they take too much damage or get killed by the Quietus, Wraithverge, or Bloodscourge weapons.
