Hate Plus is a direct sequel to the game Analogue: A Hate Story, created by Christine Love. It's a dark visual novel about history, gender, transhumanism, civil liberties, baking, cosplay, and above all, hate.
It features new art and costumes, an all new soundtrack (plus theme song “It’s Not Ero!!”) from Isaac Schankler, a whole new and improved UI, and more writing than Analogue did.
