Play Nemesis (ROM version) Online

I first played Nemesis on MAME, the arcade emulator, years after its 1985 arcade release. Konami developed it, and it fits right in with the other methodical shooters of that era, where pattern recognition mattered more than pure speed. It doesn't try to overwhelm you with chaos from the start; it builds its challenge deliberately.

You pilot a ship through horizontally scrolling stages, shooting down alien craft and dodging their precise, patterned attacks. The main goal is simply survival, pushing further into each level to confront the large, screen-dominating bosses. A key mechanic is the power-up system; defeated carriers drop icons that cycle through different weapon types, and you must grab them at the exact moment your desired weapon is displayed. Another is the option, a smaller satellite ship that follows your movements and doubles your firepower, but can be lost if you take a hit. The pacing is measured, demanding careful positioning and timing over frantic button mashing. It feels like a tense, strategic duel where every mistake has clear consequences.
