I Love Bees was an alternate reality game (ARG) that served as a real-world experience and viral marketing campaign for the release of developer Bungie's 2004 video game Halo 2. The game was created and developed by 42 Entertainment. Many of the same personnel had previously created an ARG for the film A.I. titled The Beast. I Love Bees was commissioned by Microsoft, Halo 2's publisher and Bungie's ultimate parent company at the time.
