Frank O'Connor, or Frankie, is the Franchise Development Director of the Halo franchise at 343 Industries. Previously, he has worked as the content manager for Bungie. He was the primary writer of the Bungie Weekly Update through the production of Halo 2 and Halo 3, as well as the creator of Mister Chief. He announced his departure from Bungie on May 16, 2008 in order to work more closely with Microsoft Studios on Halo-related content.
O'Connor was a co-author of Halo: Evolutions - Essential Tales of the Halo Universe, providing the introduction and the short stories Midnight in the Heart of Midlothian and Soma the Painter. In addition, he authored the digital novel Halo: Saint's Testimony. O'Connor also wrote the stories Dominion Splinter and The Ballad of Hamish Beamish in Halo: Tales from Slipspace and Halo: Fractures, respectively. Saint's Testimony was also included in Fractures.
He is originally from Edinburgh, Scotland, where he was born and raised. Growing up Frankie was obsessed with playing games: Pong, 2600, Intellivision, Vectrex, ColecoVision, Sinclair Spectrum, Atari 800, Commodore 64 and so on, until Xbox 360 in the present day. He didn't have them all at the same time, upgrading when the next generation of systems was released.
He was able to parlay his love of video games into a career working at a number of video game magazines including Ultimate Future Magazine, TOTAL! Nintendo Magazine and the Official Xbox Magazine. He then made the jump to Bungie Studios as content manager. Asked about his typical day at the office Frankie told HIH:
