Curse is a 1989 shoot 'em up game originally released in Japan only. A US release was planned, but never came through. Now you can play it on your US console as this reproduction game is a region free cartridge.
It was a sideways scrolling shoot 'em up spread across five levels. Curse is similar to many other sideways/horizontal scrolling shooters, most notably R-Type. Various power-ups can be collected to boost weapons and speed. The object of the game is to shoot all other enemies that appear on screen and avoid crashing into bullets, enemies or foreground scenery. There are end-of-level boss enemies that stay with the player until they are defeated. There are no difficulty settings but the extends (aka: 1ups) are awarded every 1 million points.
