I Love Bees was an alternate reality game (ARG) that served as both 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.

Halo 2 is a 2004 first-person shooter game developed by Bungie and published by Microsoft Game Studios for the Xbox console. Halo 2 is the second installment in the Halo franchise and the sequel to 2001's critically acclaimed Halo: Combat Evolved. The game features new weapons, enemies, and vehicles, another player character, and shipped with online multiplayer via Microsoft's Xbox Live service. In Halo 2's story mode, the player assumes the roles of the human Master Chief and alien Arbiter in a 26th-century conflict between the United Nations Space Command, the genocidal Covenant, and later, the parasitic Flood.
