One One Se7en is a Halo-themed webcomic written by Stuntmutt. It is currently hosted by halo.bungie.org. First published on June 22, 2003, it is easily recognized by its distinctive portrayal of John-117 and other Halo characters. Over the years, One One Se7en has had many crossovers with other webcomics.
There are several One One Se7en-themed Flash games created by halo.bungie.org member Boll: a game titled Warthog Launch, which was also included in the bonus disk that came with the Limited and Legendary Editions of Halo 3, and CrazyBOLL, a side-scrolling game that was used in a HBO-hosted contest for access codes for the Halo: Reach multiplayer beta.
