Play Metroid Zero Mission : Boss Rush Mode Online

Metroid Zero Mission came out on the Game Boy Advance in 2004, developed by Nintendo R&D1. It was a full remake of the original NES game, but it also included a separate Boss Rush mode, which was a great extra for players who had already finished the main story. This mode stripped away the exploration and just focused on the combat, which was a pretty common bonus feature in games from that era.

You control Samus Aran and face every major boss from the game in a fixed sequence. The main objective is simple: survive every fight without dying, using all the weapons and abilities you've collected. Key mechanics include using the Morph Ball to dodge attacks, firing missiles to break enemy armor, and managing your energy reserves carefully between battles. The pacing is relentless, and the difficulty is high, since a single mistake can force a full restart. It feels like a pure test of your reflexes and memory for each boss's patterns.
