Giants: Citizen Kabuto is a third-person shooter video game with real-time strategy elements. It was the first project for Planet Moon Studios, which consisted of former Shiny Entertainment employees who had worked on the game MDK in 1997. Giants went through four years of development before Interplay Entertainment published it on December 7, 2000, for Microsoft Windows; a Mac OS X port was published by MacPlay in 2001, and the game was also ported to the PlayStation 2 later that year.
