潜水艇
Submarine is an action arcade game released in 1985 by Sigma Enterprises Inc. Players control a submarine navigating underwater environments, tasked with destroying enemy vessels and avoiding incoming threats. The gameplay involves maneuvering the sub to fire torpedoes at surface ships and other underwater enemies while dodging depth charges and hostile fire. The controls are straightforward, typically handling movement and weapon firing. As players progress, enemy attack patterns become more frequent and intense, increasing the challenge. The game features a scoring system that rewards players for each enemy destroyed. Sigma Enterprises Inc. designed the cabinet as a dedicated arcade unit, giving players an immersive underwater combat experience typical of mid-1980s arcade action titles.
