Dungeon Explorer II[a] is an action role-playing video game developed and originally published by Hudson Soft for the TurboDuo in Japan on March 26, 1993, and in North America by Turbo Technologies in October of the same year.

Dungeon Explorer II was met with mostly positive reception from critics and reviewers alike since its initial release on the TurboDuo, with praise directed towards the graphics, audio, gameplay and multiplayer.

[21][1][26] Public reception was also positive; Readers of PC Engine Fan voted to give the game a 23.53 out of 30 score and ranking at the number 63 spot in a poll, indicating a large popular following.

They praised the voice acting and "menacing" sound effects, and said that though the enemies and bosses are both excessively easy to defeat, the length of the game is enough to satisfy RPG enthusiasts.

They also praised the five-player support and the gambling minigame, and while agreeing that the combat is not particularly difficult, argued that figuring out which characters must be talked to in order to progress the adventure is very challenging.

[22] Joypad's Grégoire Hellot and Jean-François Morisse commended the graphics, character animations, sound design, controls and multiplayer but criticized its lack of originality.

[23] Mega Fun's Stefan Hellert and Martin Weidner felt that the visuals were similar to the first game but gave positive remarks to the atmospheric soundscape and multiplayer but criticized its light role-playing elements and repetitive gameplay.
