Scramble Spirits (1988)

Sega's take on the 1943 style of vertically scrolling shoot 'em ups was set in the future. Your fighter plane is aged and under-powered, yet you must face down large planes, tanks and ground targets to achieve victory. Each level ends with a close-viewed section of particular intensity before finally facing a boss. Smart bombs are occasionally found lying around, and can destroy everything on the screen, although you can't use them on the bosses. A simultaneous 2-player mode is provided.
