Heretic II

Unlike previous games in the Heretic/Hexen series, which were first-person shooters, players control Corvus from a camera fixed behind him in the third-person perspective. Players are able to use a combination of both melee and ranged attacks, similar to its predecessor. While there are still three weapons the player can collect that each use their own ammo, they also have the ability to use several offensive and defensive spells that draw from pools of green and blue mana, respectively. The Tome of Power is no longer an item scattered around the levels, but a defensive spell that still works in the same manner as the other games in the series by improving damage and granting weapons and offensive spells new abilities for a limited time.

Melee combat is also more varied, with the ability to perform several attacks using Corvus' bladestaff and cut off the limbs of enemies, rendering them harmless. Players are also able to utilize magical shrines throughout the game that grant a variety of effects upon use, such as silver or gold armor, a temporary boost in health, a permanent enhancement to the bladestaff, etc.

Corvus, the protagonist of the first game, returns from his banishment and finds that a mysterious plague has swept the land of Parthoris, taking the sanity of those it does not kill. He returns to his hometown of Silverspring but is forced to flee after the infected attack him, becoming infected himself in the process. The effects of the disease are held at bay in Corvus’ case because he holds one of the Tomes of Power, but he still must find a cure before he succumbs.

His quest leads him through the city and swamps to a jungle palace, then through a desert canyon and insect hive, followed by a dark network of mines and finally to a castle on a high mountain where he finds an ancient Seraph named Morcalavin. Morcalavin is trying to reach immortality using the seven Tomes of Power, but he uses a false tome, as Corvus has one of them. This has caused Morcalavin to go insane and create the plague. During a battle between Corvus and Morcalavin, Corvus switches the false tome for his real one, curing Morcalavin's insanity and ending the plague.

The game was in development since November 1997 by a team of 20 people. Inspired by the Tomb Raider series, Raven Software decided to make use of the Quake II engine to create a third-person action game. A major step in the early development was Gerald Brom's concept art. In a month, the company had programmed the game's camera system. After Activision's approval of the game's demo, Raven Software aimed to get the full game finished by Christmas (it would release just prior to that Thanksgiving).

The team considered leaving out the Quake II engine's software renderer, but ultimately decided both to retain it and enhance it to support 16-bit color.

Despite positive reception from critics, Heretic II was a commercial failure. According to PC Data, its sales in the United States totaled 28,994 units by April 1999. Activision's Steve Felsen blamed this performance on the game's design: he noted that "fans of first-person shooters—the target audience for this game—stayed away due to the third-person perspective".

Next Generation reviewed the PC version of the game, rating it three stars out of five, and stated that "Heretic II has a lot going for it. It easily earns it space on the shelf with the heavy hitters this season, but it also serves as a reminder to all that every aspect of game design needs to be pushed if you want your project to truly stand out".
