Play Codename Kids Next Door Volume 1 - Gameboy Advance Video (U)(Rising Sun) Online

Codename Kids Next Door Volume 1 was released for the Game Boy Advance in 2004 by The Code Monkeys and published by Majesco. It arrived during a period when licensed games based on animated series were common on the handheld, offering fans a portable extension of the show's universe without much pretense or complexity.

You control one of the five main KND operatives, each with a unique weapon like Numbuh One's water gun or Numbuh Five's slingshot. The goal is to fight through waves of adult villains, from dentists to rebellious teenagers, across side-scrolling stages. Signature mechanics include switching between team members on the fly to exploit enemy weaknesses, and using special team-up attacks that drain a shared energy meter. The pacing is fast and chaotic, with enemies swarming from both sides, and the difficulty can spike unexpectedly in later levels. It feels like directing your own frantic, miniature cartoon brawl.
