Game Boy World #053: Mercenary Force [Live Planning/Lenar/Meldac, 1990]

As we enter the holiday season, Game Boy World gives us reason to celebrate at last: Not only a game that doesn't incorporate a single puzzle element, but a well-made and quite high-quality one at that! Mercenary Force puts a unique spin on the shoot-em-up, not only in terms of mechanics but also with its setting. It's wicked hard, but so good.
