[3] The organization first participated in competitive Tom Clancy's Rainbow Six Siege (R6), joining the scene in November 2018, after acquiring SK Gaming's roster.

[4] In competitive R6 play, the team won the tenth season of the North American Rainbow Six Siege Pro League in 2019.

[12] In October 2024, DarkZero earned a spot at the BLAST R6 Major Montreal tournament after defeating M80 in the North America League 2024 Stage 2 semifinals.

[16] They introduced a new roster lineup in April 2022,[17] which included ScrewFace, Ange, Trick, drone, and ZexRow, as well as neilzinho serving as head coach.

[21] In July 2022, the Japanese esports organization Reignite dissolved its Apex Legends roster, which consisted of Rhys "Zer0" Perry, Noyan "Genburten" Ozkose, and Rick "Sharky" Wirth.

[30][31] With TSM and OpTic engaging in a "chaotic endgame", DZ won out against Spacestation and GMT in the final circle of the championship match.

[25] Their ALGS Championship victory came so soon after their official signing with DarkZero, that the organization had not yet updated their website to include bios for the players.

[32] In April 2023, during the middle of the 2022–23 (ALGS Year 3) season, Sharky left the team, expressing he lost passion for Apex; Beau "RamBeau" Sheid would fill-in for DarkZero's vacant roster spot.

[34] Following the end of the ALGS Pro League regular season, RemBeau was left off the DZ roster and the organization instead picked up Rody "Xynew" Geissler as their third player.

[34] Just shortly prior to the ALGS Year 3 Split 2 Playoffs, the team dropped PVPX and picked up coach "zz".

[47] On May 14, it was announced that Zer0 and Genburten would join with ImperialHal to form a "superteam" for Year 4 Split 2, though it was initially unclear if this was to be under DarkZero or as part of a different organization.

[50] In light of this move, DarkZero opted to release Sikezz, as well as zz, and their analyst "Privacy", as the org reevaluated its Apex position.
