Play Duel Masters : Shadow of the Code Online

Duel Masters: Shadow of the Code came out for the Game Boy Advance in 2005, developed by Mistic Software and published by Atari. It was part of that wave of tie-in games that tried to capture the feel of the card game and anime, but it did its own thing with a story-driven adventure. You don't just duel; you explore a city under siege, talking to people and getting into scraps in back alleys.

You control a young duelist trying to find a missing friend while fending off rogue creatures. The main goal is to uncover a conspiracy by battling through urban zones, not dungeons, and gathering intel from NPCs. Signature mechanics include real-time combat where you summon monsters to fight for you, a simple stealth system for avoiding patrols, and using a scanner to reveal hidden clues in the environment. The pacing is brisk, with frequent interruptions from rival duelists that keep you on your toes. It feels like a compact, slightly janky detective story wrapped in a monster battling game.
