The Binding of Isaac
Determination: Explicit — Denial 3, Blasphemy 3, Occult 2
A mother hears the voice of God telling her to kill her son, and that is the premise, not the twist.
Edmund McMillen built The Binding of Isaac on Genesis 22 and kept the title. Isaac's mother, described as devout and shown watching Christian broadcasting, hears a voice the game identifies as God's, telling her first to strip her son of worldly things, then to isolate him, then to sacrifice him as proof of her faith. Isaac escapes into the basement, and the game is the descent. Scripture supplies the mechanics rather than the flavour: the Bible is an item, effective enough to kill Mom outright; the Four Horsemen are bosses; Satan and Mega Satan are endgame encounters; and Devil Rooms offer demonic items in exchange for the player's own heart containers, which is usually the stronger play.
