Hexen II is a dark fantasy first-person Hack and Slash developed by Raven Software from 1996 to 1997, published by id Software and distributed by Activision. It was the third game in the Hexen/Heretic series, and the last in the Serpent Riders trilogy. It was made available on Steam on August 3, 2007. Using a modified Quake engine, it featured single-player and multi-player game modes, as well as four character classes to choose from, each with different abilities. These included the offensive Paladin, the defensive Crusader, the spell-casting Necromancer, and the stealthy Assassin.

Improvements from Hexen and Quake included destructible environments, mounted weapons, and unique level up abilities. Like its predecessor, Hexen II also used a hub system. These hubs were a number of interconnected levels; changes made in one level had effects in another. The Tome of Power artifact made a return from Heretic.
