Dolphine Blue

Dolphin Blue is a classic 2D side-scrolling run-and-gun arcade game developed by Sammy for the Atomiswave arcade system.
Set in a futuristic world devastated by war, the game follows two heroes, Erio and Anne, as they battle through enemy forces, military bases, and dangerous environments to stop a powerful evil organization.
Armed with powerful weapons and accompanied by a friendly dolphin, players fight waves of enemies, dodge explosions, and face massive mechanical bosses.
The game combines fast-paced shooting, colorful 2D graphics, exciting underwater sequences, and intense arcade action, delivering a nostalgic experience reminiscent of classic games like Metal Slug.
