Gauntlet Legends

Gauntlet Legends is a 3D Action/RPG based on the classic series. You have a choice between four basic characters: Warrior, Valkyrie, Archer ("Elf") and Wizard. There are also several bonus characters. The game is broken up into five "worlds" with several levels in each world. Your goal is to find obelisks and rune stones used to restore the power of Sumner so he can defeat the evil demon Skone. You gain levels by killing enemies, and with each level your stats improve. The game's success led to an expansion of sorts, Gauntlet Dark Legacy, which includes new characters and worlds as well as those from Gauntlet Legends.

Story
In ages past, a corrupt mage named Garm used a set of Runestones to summon a demon named Skorne (it is not stated what Garm intended to use Skorne for; however, as Gauntlet Legends introduces Garm as a "greedy young mage", it can be assumed he wanted Skorne for his own personal gain). However, Skorne crushed Garm and imprisoned his soul in the Underworld. Skorne, fearing the power of the Runestones, scattered them throughout the four realms, so that they could never be used against him. The player(s) must defeat the end bosses of each of the four realms to obtain the four keys which allow access to Skorne's temple. While traveling through each realm, players must also collect the Thirteen Runestones from where they have been scattered. The complete set of Runestones allows players to pursue Skorne to the Underworld in order to finally destroy him.
