Play Nemesis (Japan) Online
You weave through tight corridors dodging bullet sprays, grabbing power-ups to beef up your pea shooter—until some sneaky Moai head ruins your run. Classic Gradius chaos squeezed into a Game Boy screen, complete with those brutal Konami difficulty spikes.

Konami released Nemesis for the Game Boy in 1990, a time when handheld games often felt like smaller, simpler versions of their console counterparts. This one stood out for bringing a full horizontal shooter experience to the pocket, with the kind of detailed sprite work and relentless enemy patterns the developer was known for. It wasn't just a port; it felt built for the hardware, a serious attempt to translate the intensity of the genre onto a monochrome screen.
You pilot a ship through side scrolling stages filled with waves of enemies and environmental obstacles. Your main objective is to survive, destroying everything in your path while collecting power up capsules to enhance your weapons, like the classic Options that mirror your attacks. The game progresses screen by screen, demanding careful navigation and memorization of enemy spawn points. The pacing is fast, and the difficulty is steep, typical of Konami's shooters from that era. It feels tense and demanding, a genuine test of focus and reflexes where every mistake is punished immediately.
