http://hellrising.comHell Rising is a post-apocalyptic browser-based MMORPG inspired by Urban Dead. The game is set within a quarantined city of which the inhabitants have been mutated by a special type of fungal infection. You can play as either a human, zombie, or a unique infected type known as a vampire. You may choose to attempt survival as a human, or hunt those that do as one of the undead, but death only means you continue your existence as a different kind of monstrosity.
