Russel David Kevin Van Dulken (born November 14, 1999), better known as Twistzz, is a Canadian professional Counter-Strike 2 player for Team Liquid.

In December 2015, Twistzz joined SapphireKelownaDotCom along with veteran In-Game Leader Kyle "OCEAN" O'Brien.

[6] In January, TSM released Twistzz along with his teammates allowing Misfits Gaming to pick up the roster.

In January, Twistzz's Liquid placed 14th at the ELEAGUE Major: Boston 2018 with their coach Wilton "zews" Prado standing in for Lucas "steel" Lopes, due to roster-lock rules at the time.

Liquid would face HellRaisers yet again winning 2–1 with Twistzz amounting to a Performance Rating 2.0 of 1.16, going through into the Semi Finals of the second Major of 2018.

However, Liquid would win SuperNova CS:GO Malta which did have the caveat of not having Astralis in attendance and was not considered a High Tier tournament.

[14] In June, Liquid won DreamHack Masters Dallas 2019 and the ESL Pro League Season 9 Finals, beating their rivals Astralis in the round of 6.

[15] At ESL One Cologne 2019 Liquid won the Intel Grand Slam worth $1 million in addition to the tournament itself.

[16] Despite Team Liquid coming into the Starladder Berlin Major as heavy favorites, they scraped out of the group stage 3–2, and lost to Astralis in the quarterfinals.

[19] Twistzz had mostly mediocre results for the rest of 2021 with FaZe Clan other than an impressive showing at IEM Cologne 2021, finishing in a respectable 3rd-4th position in the first CS:GO LAN event since the start of the COVID-19 pandemic.

After two disappointing results post-Major,[26] the FaZe team played in the online Roobet Cup, where they finished second, losing to BIG Clan.
