Dangun Feveron[a] is a 1998 vertical-scrolling shooter arcade game developed by Cave and published by Nihon System in Japan.

The disco theme was chosen after Cave received negative feedback from location testing, and wanting the game to have its own unique ideas and mechanics.

Its plot involves an organization named the Great Gracce attempting to seize control of Earth as part of its plan to conquer the entire universe.

The residents of a nearby planet named Fever are alerted of this, and deploy a group of starfighters to destroy the Great Gracce and its leader before they take Earth and its population captive.

The game features a disco-inspired presentation, which serves importance to the gameplay through "cyborg soldiers", miniature people that can be collected to increase the score multiplayer.

[4] Feveron was originally a more generic take on the shooter genre, but the team wanted it to have its own unique presentation and mechanics after the game returned generally unfavorable results at location tests.

Around the time the disco theme was considered, a member of the development staff believed the music should represent the game's fast-paced action.

[6] The soundtrack was then hurriedly changed to feature disco-inspired music tracks, though the boss battle theme retained the heavy metal sound.

[3] Takehiko Hara, who previewed the game for ITmedia, claimed the low difficulty made Dangun Feveron more accessible to beginners, as most scrolling shooters at the time were known for their immense challenge.
