According to Bungie's most recent weekly update, the team has begun testing elements of Halo 3's single-player campaign. The testing is currently focused on gameplay, specifically, AI encounters.Bungie's Frank O'Connor details a run-in with a pack of Grunts who had wisely flanked Frankie while he was distracted by "something bigger than a Grunt." Frankie describes the Grunts' tactic as "quite a shock," given that their behavior in the past has been half-witted. Frankie reminds us, "Lots of folks focus on what technology can do for the appearance of a game -- but the 360's prodigious horsepower can also be applied to AI."
