U4X eSports entered the Halo scene in June 2016, signing the, at the time, EU Pro League 1st place Online Warriors team consisting of Robby "Kimbo' Faulk, Luciano "Mose" Calvanico, Brandon "Respectful" Stones and Arkel "Snakey" Brown. Despite a nearly perfect 6-0 start to the season with only one game loss, U4X made a roster change after Week 3, dropping Snakey and replacing him with X-Men's Perry "TuFoxy" Kenyon. At the conclusion of the season, U4X held a nearly perfect 10-0 record with only 4 dropped maps, finishing 1st overall. Shortly after, the roster was acquired by FAB Games eSports.
