Fiend (Qtest)

The skin of the Demon is less detailed. Both the code and the model for this creature exist in Qtest. The Fiend is far larger in Qtest than the final version of the game, being more to scale with the Shambler.

The Fiend is somewhat bugged in its animations, meaning it is able to leap towards the player, but said leaping can result in the game crashing. Furthermore, the Fiend lacks a close-range melee attack, meaning the player can easily kill one by standing next to the Fiend (made easier by the fact that the Fiend follows the player).
