Secret Agent Barbie: Royal Jewels Mission on the Game Boy Advance is a surprisingly deep stealth-action platformer that stands out from typical licensed fare. Developed by Digital Illusions (DICE), the game transitions the Barbie brand into a side-scrolling adventure across global locations like London and Mexico. Players utilize a variety of high-tech spy gadgets, such as heat-vision goggles and remote-controlled robots, to solve environmental puzzles and avoid detection. Unlike many contemporary titles, it emphasizes non-violent problem-solving and careful navigation over combat. For collectors, this title is a fascinating artifact as an early project from the team that would later create the Battlefield series. It offers a competent entry-level stealth experience with fluid animations and colorful sprite work that pushes the GBA’s hardware. Whether for nostalgic reasons or an interest in the evolution of stealth gaming, it remains a charming and technically solid addition to any handheld collection.
