Gigas Mark II
Gigas Mark II is an action arcade game released by Sega in 1986. Players control a large robotic fighter viewed from a side-scrolling perspective, battling through waves of enemies across multiple stages. The gameplay centers on combat mechanics where the player uses punches, kicks, and special attacks to defeat opponents. The robot character has a substantial on-screen presence, and enemies approach from multiple directions, requiring players to manage positioning carefully. Each stage presents different enemy types and escalating difficulty. The game uses a joystick and button configuration typical of arcade cabinets of the era, with inputs mapped to various attack moves. Sega designed the experience around quick arcade sessions, with score accumulation driving replayability.
