User Summary: Requiem: Memento Mori is a horror-themed free-to-play MMORPG by Gravity. Players can choose between 4 races and 8 starting classes which each later branch into 2 specializations. The game features an accelerated day-night cycle with an "hour" of Nightmare time when more powerful monsters spawn in many corners of the world. Certain nightmare monsters have a chance of dropping special parts which may be combined by the player into a possession beast - a powerful alternate form the player can assume every time his hardcore gauge has filled completely.
