Gauntlet

(User summary)

Originating with the titular 1985 arcade cabinet game, the Gauntlet series covers multiple games that span over 2 decades of platform development. Due to its popularity, the original "Gauntlet" title was ported from the cabinet to many home platforms of the 80s, and several sequels were subsequently released, first in 2D, then isometric, then finally full 3D. However, across all versions the gameplay remained familiar - a fantasy themed hack-and-slasher, the player(s) would need to explore, collecting food, magic and keys whilst destroying swarms of monsters (and their associated generators / spawn points) to find each level's exit.
