Oxygen Esports unveils new Rainbow Six Siege roster

Oxygen Esports has rounded out its Rainbow Six Siege competitive roster after signing Roman ‘Forrest‘ Breaux, Pablo ‘Gryxr‘ Rebeil and Adam ‘Atom‘ Gutierrez.

Only time will tell whether the new roster will push the American organisation beyond to the top of R6 Siege esports this season after a top eight finish at the Six Invitational 2025.

Oxygen Esports announced the change via X on March 10th, 2025, welcoming its latest additions to its Rainbow Six Siege competitive line-up.

The three will be joining the two currently signed players for Oxygen Esports, which includes Arthur ‘GMZ’ Oliveira and Evan ‘Yoggah’ Nelson.

This is the current team composition for Oxygen Esports for Rainbow Six Siege esports in 2025:

Ethan ‘Nuers’ James, Lucas ‘DiasLucasBr’ Dias, and James ‘Hat’ Hatfield have all left the organisation following a disappointing performance at this year’s Invitational.

Forrest has been a prominent support player for Spacestation Gaming (SSG), contributing towards reaching fifth to sixth place in the last two Invitationals, including the recent tournament won by FaZe Clan.

On X, Forrest said: “Saying I’m grateful to be a part of SSG is an understatement. The experiences we had together, the culture we developed truly was and still is something special, especially within the realm of esports. With all things in life, change is inevitable.

“As far as my future within Siege, I’m excited to take on my next challenge head on and show what I’m capable of and with those around me.”

Atom is an upcoming player who has been rapidly making the rounds in the esports scene. He climbed from MKERS to Unwanted, who reached fourth place in this year’s Invitational.

Gryxr played for Soniqs since 2022. He joined Shopify Rebellion near the end of last year, before his departure was announced on February 28, 2025 through X.

Gryxr said: “Excited to start a new journey with a hungry group of lads. Blessed to be given the opportunity by them and can’t wait to see what we can achieve.”

Fans will have to wait and see if this will prove to be a stronger team than before, considering the shaky future the organisation is up against.
