Oxygen Supremacy is a Canadian esports organization.
Halo 5: Guardians
Oxygen Supremacy made its entry into the Halo scene on May 10, 2017, acquiring the top amateur team known as TBD and consisting of Ryan "RyaNoob" Geddes, Troy "DasTroyed" Dusman, Cody "ContrA" Szczodrowski and Kyle "Nemassist" Kubina with coach Joshua "Mash" Mashlan. At UMG Daytona, Oxygen Supremacy came out hot, going undefeated in the Open Bracket and upsetting Luminosity Gaming and Str8 Rippin early in the Championship Bracket. They went up 2-0 against 2nd seeded Team EnVyUs in the Winners Semifinals, but could not hold the lead as NV came back and won the series 3-2. In Losers, Oxygen were unceremoniously swept by Splyce and sent home with a top 6 finish. The following week, Oxygen Supremacy competed in the Pro League Last Chance Qualifier and finished in 2nd place, falling 4-2 to Splyce in the Grand Final and missing out on a Pro League spot. Forced to compete in the Open Circuit, Oxygen dominated, winning all four Legendary Cups. At DreamHack Atlanta, Oxygen finished second in the Relegation tournament, qualifying for the Fall 2017 Pro League. They finished in the top twelve in the main tournament. The Oxygen roster was acquired by Naventic during the offseason.
Oxygen Supremacy returned to Halo in the midst of the Halo World Championship 2018 season on February 8, 2018, acquiring the North American roster of Timothy "Rayne" Tinkler, Ezekiel "Prototype" Martinez, Cory "Str8 SicK" Sloss, and a returning RyaNoob. They went into MLG Orlando as the eighth seed, ultimately finishing in the top eight. Oxygen again finished second in their pool at MLG Columbus, earning a berth at Halo World Championship 2018 in the process. They went on to finish in the top six, losing to Team Reciprocity and Splyce. At Worlds, Oxygen Supremacy lost 3-0 to both Team Reciprocity and Team Infused, missing out on the championship bracket and finishing in the top twelve. However, RyaNoob was able to win the FFA Championship.
