Developed by the infamous Color Dreams in 1990, Pesterminator: The Western Exterminator stands as one of the stranger artifacts in the NES library. It is an unlicensed promotional title commissioned by the real-world Western Exterminator Company, featuring their long-standing mascot, Kernel Kleanup. Players navigate the top-hatted exterminator through various bug-infested locales, ranging from standard suburban homes to surreal environments like the Moon and a futuristic space station. While corporate tie-in games were a growing trend in the early 90s, the unlicensed nature of this release gives it a distinct, rough-around-the-edges feel common among Color Dreams' non-Nintendo-sanctioned catalog.
The gameplay follows a standard side-scrolling platformer template where the Kernel uses his oversized mallet to crush ants, mice, and other vermin. Controls are notoriously stiff, with jump physics that feel floaty and hit detection that is often more a matter of luck than precision. The level design is relatively linear but frequently suffers from "blind jumps" and repetitive enemy patterns that lead to quick frustration. Despite its mechanical flaws, there is a certain charm to the absurdity of smashing giant insects while wearing a Victorian-style suit, though the lack of polished game design prevents it from being truly enjoyable for long stretches of time.
Visually, the game is a mixed bag of bright palettes and muddy sprite work. The Kernel himself is surprisingly well-defined, but the backgrounds often feel cluttered and lack the artistic cohesion found in licensed Nintendo titles. Sound-wise, the music is a loop-heavy chiptune affair that becomes grating within minutes, accompanied by sound effects that lack any real impact. Collectors usually seek this title out more for its status as a bizarre piece of marketing history and its unique cartridge shell rather than for the actual gameplay experience, which remains firmly in the "unlicensed curiosity" category.
