Abadox is a visceral and notoriously difficult side-scrolling shooter developed by Natsume. In the year 5012, a giant alien organism known as Parasitis has swallowed the planet Abadox. As Second Lieutenant Nazal, you must fly into the creature's digestive tract to rescue Princess Maria and destroy the alien from within. The game is famous for its unique biological aesthetic—enemies look like brains, eyes, and internal organs—and its challenging gameplay where a single hit resets your progress. Featuring both horizontal and vertical scrolling stages, Abadox is a cult classic for shmup fans seeking an intense challenge.
