Sopwith

Sopwith is a side-scrolling shoot 'em up created by David L. Clark of BMB Compuscience in 1984. It was originally written to run on the IBM PC under MS-DOS. The game involves piloting a Sopwith biplane, attempting to bomb enemy buildings while avoiding fire from enemy planes and various other obstacles. Sopwith uses four-color CGA graphics and music and sound effects use the PC speaker. A sequel with the same name, but often referred to as Sopwith 2, was released in 1985.
