Gauntlet Legends

Gauntlet Legends is a three-dimensional dungeon crawler arcade game that was released by Atari Games in 1998, based on their classic Gauntlet series. It runs on that company's Vegas hardware (an MIPS R5000 that runs at 200 MHz, with an Analog Devices ADSP-2104 that runs at 16 MHz), and the players have a choice between four basic characters of Warrior, Valkyrie, Wizard and Archer (elf), but there are also several bonus characters. The game is divided into five worlds with several levels each and the players' goal is to find obelisks and rune stones which shall restore the power of Sumner (this game's protagonist aside from the players) so he can defeat the evil demon Skorne. The players gain levels by killing enemies, and with every level their statistics improve. The success of the game led to an expansion of sorts, Gauntlet Dark Legacy, in 1999 (the same year this game was converted to the Nintendo 64 console by Midway Games), which featured new characters and worlds as well as those from this game. In 2000, the game was also converted to the Sony PlayStation and Sega Dreamcast.
