* BlackComedy: In spades!
** The over-the-top, karmic deaths
** The household's nonchalance regarding the obviously troubled child in their midst
** The Antichrist doing chores around the house, up to and including collecting his mother's used panties
* EvilIsCool: It is. It just is. Telekinesis, Mind Control and oh so many more deliciously evil powers. What more can you want?!
* {{Narm}}: [[spoiler:Isaac]] speaking. Sure, he's [[spoiler: an Antichrist figure equal in power to Lucius]], but it's tough to take him seriously with a generic demon-filtered voice emanating from a stiff, flapping mouth.
** "The rest of you will join us beneath the bedrock of justice!"
* SpiritualAdaptation: The setup is suspiciously similar to ''Film/TheOmen'', with the juvenile, black haired antichrist murdering people.
* UncannyValley: This is one of the few cases where limited animation works. Lucius seldom has anything but a blank expression on his face and it's '''creepy'''.
* WhatAnIdiot: The game has the eponymous character [[spoiler:taking control of his "father" Charles into killing his mother, Nancy, with a nail gun]]. At the same time, [=McGuffin=] and another police officer are present at the scene.\\
'''You'd Expect''': that he puts two and two together that Lucius is responsible for [[spoiler:taking control of his "father" and killing his mother]] and has him locked up. Happy ending, indeed.\\
'''Instead''': he comes to a conclusion that [[spoiler:Charles]] is responsible for the murder, and tries to lead chase to him. During that time, he has the other police officer watch over Lucius [[spoiler:which he does murder]]. For him, he assumes the worse after this.
