Under Defeat propels you into an alternate-World War II sky where the deadliest machines of war are prototype attack helicopters. Originally dazzling arcades on Sega’s Naomi hardware and later serving as one of the Dreamcast’s swan-song titles, this top-down vertical shooter spices up classic bullet-hell action with a unique tilt mechanic—lean your chopper slightly left or right to shift your firing angle and outmaneuver swarms of enemies. With responsive controls, explosive visual effects, and adrenaline-pumping boss encounters, Under Defeat delivers an unforgettable combat experience that demands both precision and daring.
