Challenger

Challenger was originally planned as a port of the ZX Spectrum game Stop the Express, though Stop the Express only contained the first train level, and 3 levels were added for the release of Challenger. The game's title screen displays the slogan "Realtime Action Adventure." The game is uniquely constructed, where the levels consist of a side-scrolling platform game, a top-view scrolling shooting game, and a fixed-screen action game. The game was also unique for its 100-screen map, which was extensive for its time.
