Overlord: Raising Hell

The plot takes place right after the events in the original Overlord where Gnarl reports evil energy being emitted from the Overlord's various conquered lands. Upon his arrival in the Mellow Hills, the peasants of Spree surround a large portal, which they believe to be a passage to Heaven. Upon arriving, however, they end up in the "Abyss", an alternate hell version of their own lands where they are tortured or forced to work. In the Mellow Hills Abyss, the now fallen Halfling hero Melvin Underbelly, previously slain by the Overlord in the last game, is being punished by becoming even more gluttonous than before, constantly eating to the point of exploding, yet returning to the Abyss to restart the same process endlessly.

Luring him with food, the Overlord uses Melvin's torture as a method of blowing through the Abyss's defenses. Melvin ends up rolling into a hole, there unable to eat anything but mud and earthworms. The Overlord secures the Abyss stone, which allows him to take control of the dimension.

The Overlord: Raising Hell expansion was initially announced for digital download on Xbox 360's Xbox Live marketplace on November 1, 2007 for an eventual release in same month, at least in Germany. Though the separate add on (without base game) as downloadable content was postponed to an early 2008 release.

The PC downloadable content was to be released in the next year of 2008. A boxed product for PC, including the base game, this new expansion, Challenge Pack DLC, and split-screen multiplayer content, was released in Germany only in late 2007.

Raising Hell was met with generally positive reviews. The expansion holds a score of 72 out of 100 on Metacritic for the PlayStation 3, and a score of 75% on GameRankings.

Eurogamer continued its praise, calling it "probably one of the best games currently available on PS3". IGN however found the PS3 version to harbour many technical issues including drop in frame rate, long load times and lag in multiplayer, issues that GameSpot also found by concluding while the PS3 version is the best value for money, due to "the unpredictable frame rate, sluggish controls, and fickle camera in the PS3 version", it suggested others to "pick up the technically superior Xbox 360 version and spend a little extra to get the downloadable content". GameTrailers also found a few technical issues but concluded that "when things are clicking... With plenty of humor and a substantially long quest, players will be surprised at how enjoyable Overlord can be."
