Silk Worm
丝虫战机
Silk Worm is an arcade action game developed by Tecmo in 1988. Players control either a jeep or helicopter across multiple stages, switching between ground and aerial combat. The game features simultaneous two-player cooperative gameplay where one player operates the vehicle while the other provides mounted weapon support. Each stage presents enemy forces that must be defeated to progress. Controls allow for movement and weapon fire, with players collecting power-ups to enhance firepower. The level structure alternates between jeep missions and helicopter sequences, each with distinct enemy patterns and environmental obstacles.
