From Halopedia, the Halo wiki
Apt. 117 was a planned ongoing Halo Waypoint series in development in 2010. It was swiftly removed by 343 Industries after episode 1 released on October 10, 2010 for an undisclosed reason and was presumed cancelled.
Apt. 117 follows the antics of a boring average guy named Jeff, who lives with a Halo obsessed person named Micah in Apartment 117 in apartment complex Autumn Pillars.
