Atomic Robo-Kid on the Genesis is one of those side-scrolling shooters that looks simple at first—just a little robot blasting through tunnels—but man, those patterns get brutal fast. You start underground, weaving through tight corridors while enemies swarm from all sides, and the screen’s always pushing you forward whether you’re ready or not. The bosses? Huge, weird alien ships that fill half the screen, and you’ll probably crash into them a few times before figuring out their rhythm. It’s got that classic arcade vibe where every death feels like your fault, even when it totally isn’t.
