Sea Fighter Poseidon
海战波塞冬
Sea Fighter Poseidon is a fighting arcade game developed by Taito Corporation in 1984. Players control a fighter engaged in hand-to-hand combat against opponents in underwater-themed stages. The game features directional movement and attack buttons for executing punches and kicks. Matches progress through multiple rounds against increasingly difficult opponents. The combat system relies on timing and positioning, with fighters able to move horizontally across the screen. Players advance through sequential levels by defeating each opponent to face the next challenger. The arcade cabinet presentation emphasizes competitive one-on-one fighting mechanics typical of early 1980s arcade fighting games.
