Play Battle Unit Zeoth (USA, Europe) Online
You control a massive, slow-moving mech, blasting through swarms of tiny enemies—feels like stomping through an alien warzone on that tiny green screen.

Battle Unit Zeoth came out for the Game Boy in 1991, published by Jaleco. It was part of that early wave of portable action games, where developers were still figuring out how to make something substantial on a handheld. You don't hear about it too often, but it has a specific kind of charm if you're into mechs and straightforward shooting.
You pilot a large, slow-moving battle unit through a series of side-scrolling levels, destroying everything in your path. The main goal is to reach the end of each stage while fighting off waves of smaller enemy robots and vehicles. Two key mechanics define the action: you can switch between a standard forward shot and a limited-use screen-clearing bomb, and you collect power-ups to enhance your main weapon's strength. The pacing is deliberate, almost heavy, and the difficulty can spike with some aggressive enemy patterns. It feels like methodically carving a path through relentless opposition.
