Fever S.O.S.

Fever SOS is a 2D arcade vertical scrolling space shooter in danmaku/bullet hell style. 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 player chooses one from 3 fighters and 1 from 3 types of "Powerful shot" (available by pressing the shoot button), and ship's speed. Gameplay is pretty typical (fly forward / shoot enemies / collect items / destroy bosses), but the player can capture "disco-man" - people, who are dropping from destroyed ships, required for scoring.
