Hexen II is a first-person shooter 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.
An expansion pack called Hexen II Mission Pack: Portal of Praevus was released in 1998 featuring new levels, new enemies and a new playable character class, The Demoness. It focuses on the attempted resurrection of the three Serpent Riders by the evil wizard Praevus, and takes place in a fifth continent, Tulku, featuring a Sino-Tibetan setting.
The expansion features new quest items, new enemies, and new weapons for the Demoness. She is the only player class to have a ranged starting weapon, whereas all other characters start with melee weapons. It also introduced minor enhancements to the game engine, mostly related to user interface, level scripts, particle effects (rain or snow), and 3D objects. Portal of Praevus also features a secret (easter egg) skill level, with respawning monsters. The only released patch for the expansion added respawning of certain items (such as health and ammo) in Nightmare mode, so that it would be slightly easier for playing.
