Silent Assault

Silent Assault is an unlicensed game created for the Nintendo Entertainment System published by Color Dreams. It was developed and released by Thin Chen Enterprise under two names: Sachen for its 1989 asian release, and Joy Van for its 1990 North American release.

The game uses palette swapping (different looking enemies that behave the same way) in many of the levels to minimize the number of unique enemies in the game, but give visual differences. These changes are usually made to fit the theme of the level (i.e. the theme park has clowns instead of soldiers).
