SubZero started playing Halo in 2007 with the release of Halo 3.
After a top 24 placing at HCS Indianapolis 2015 in Halo 2: Anniversary, SubZero (then known as "Penguin") broke into the big leagues in late 2015 with the release of Halo 5: Guardians. He initially joined the Noble eSports roster alongside ContrA, Rayne and FilthyG with the intent of competing in the Halo World Championship 2016 NA qualifier series. After a series of team changes, the Noble roster ended up consisting of Penguin, Rayne, Calm and Swift Kill. Noble qualified for the NA Regional Finals as the 7th seed. At NA Regionals, Noble finished top 8, qualifying for Halo World Championship 2016. Between Regionals and Worlds, the Noble roster got into a dispute with the organization, resulting in the players leaving to join Team eLevate. At Worlds, eLevate won their group, sweeping Denial eSports in the process. They then defeated Epsilon eSports in the quarterfinals and lost to Team Allegiance in the semifinals, taking a top 4 finish. Penguin was able to make multiple flashy individual plays and was praised for them during the event. Afterwards, it was revealed Penguin had the highest K/D ratio out of any player at HWC.
After Worlds, Penguin joined Renegades alongside Ninja, Victory X and Commonly. This roster qualified for the Summer Pro League with a 2nd place finish in their group at the Summer Qualifier. At the conclusion of the season, Renegades sat at 4th place in the standings, good enough to qualify for the Season Finals. On July 25th, Penguin and the rest of the Renegades roster departed to join Cloud9. At the Season Finals, C9 finished 4th, taking home $15,000.
During the off-season, the 4th place roster dropped Ninja and Victory X, replacing them with Spartan and Penguin's former teammate Rayne. The new roster was then acquired by Spartan's previous org - Team Liquid. After a 3-3 start to the Fall Pro League season, Liquid attended HCS Orange County 2016, where they finished 3rd. Liquid ended up finishing the season with a 7-7 record, good enough for 3rd place. Weeks later, Team Liquid attended HCS Las Vegas 2016, where they nearly took 1st, defeating Team EnVyUs in the Winners Finals before EnVy came back to take two consecutive series and steal the event from Liquid. At the Season Finals, Liquid were only able to win against Str8 Rippin and placed 3rd out of the four teams in attendance.
Liquid made changes in the offseason, replacing Spartan and Commonly with Eco and StelluR. The new roster's first event was UGC St. Louis 2017, where they proved they were a team competing for 1st place as they nearly defeated OpTic Gaming in the Winners Finals before taking out #1 seeded Team EnVyUs in the Losers Finals and again losing a very close series to OpTic in the Grand Finals. At ME Las Vegas 2017, Liquid qualified for Halo World Championship 2017 after sweeping Pnda Gaming, and solidified themselves as the #2 team in North America with two dominant victories over Team EnVyUs. They lost to OpTic Gaming 4-1 in the Finals and went home in 2nd place. At Worlds, Liquid were placed in a pool with Luminosity Gaming and London Conspiracy, both of whom they 3-0d to earn a top seed in the bracket. In Winners Round 1, they again defeated Team EnVyUs, this time 4-3. This was followed by a 4-0 sweep over Str8 Rippin and a 4-1 WB Finals loss to OpTic Gaming. In the LB Finals, they were unable to overcome a hot Team EnVyUs, who defeated them 4-2 to end their night with a 3rd place finish.
While Liquid made no roster changes between Worlds and HCS Daytona, Penguin rebranded, changing his game-id to "SubZero". In Daytona, Liquid faced Splyce a whopping four times over the course of the weekend - twice in pool play, of which each team won one, once in Winners Bracket Round 2, which Liquid won, and following a 5-game loss to OpTic Gaming, once more in the Losers Semifinals which was won by Liquid in a seven-game affair. They then moved on to face Team EnVyUs, looking to reclaim their spot in the top 2 after losing it at Worlds. EnVy had other plans however, sweeping Liquid in the best-of-7 and sending them home in 3rd.
