Set in the fantasy kingdom of Etrulia, Gate of Doom puts a group of four heroes (knight Carl F. Graystone, wizard Freya Edirne, bard Riger Hawk, and ninja Kirikaze) against the forces of the underworld as they try to lock the titular "Gate of Doom" forever.
The game features two-player co-operative multiplayer and a unique magic system, where the current chosen spell cycles randomly every few seconds (as shown on a spellbook underneath the player portrait). The game later received a direct sequel, known as Wizard Fire (or Dark Seal II).
The game was later ported to the Nintendo Switch on February 15, 2018 and the PlayStation 4 on August 28, 2018, both digital releases by Flying Tiger Entertainment as part of the Johnny Turbo's Arcade series. This version was later included in the Switch compilation Retro Classix Collection #1: Data East on October 1, 2020 (as well as the 2-in-1 Pack with Wizard Fire).
