This game has unused enemies.
The 2018 Agony is a dark fantasy survival horror game set in Hell, featuring demons, tortures, attractive succubi, and gore. The game's initial release got a generally-negative reception, though an improved and uncensored 18+ edition (titled Agony UNRATED) was met more warmly.
The image of the unused "Harpy" demon's model is necessarily needed.
While a slightly heavyset-looking feminine demon never appears in either version, its model is present in the game's files. Interestingly, this demon was later used in the concept gameplay video for the game's upcoming spin-off, albeit with a slight amount of different distinctive features.
