Rasmus 'sjuush' Beck entered the professional Counter-Strike scene in 2017. Initially, he played for various mix teams without achieving any notable results. In November of the same year, he signed a contract with Ambush E-Sport, helping the team win the Dust2.dk Ligaen Season 1 tournament. Afterward, the player joined Suckers, earning a gold medal at the King of Nordic - Season 10: Week #5 tournament.
In 2018, Rasmus signed with GoldenGitte, securing victories at the GameAgents Nordic Challenge and GameAgents Cup #1 tournaments. He then moved to Squared Esports, where he struggled to make a significant impact. After his contract expired, both parties mutually agreed not to extend it.
Beck didn’t remain a free agent for long and soon returned to GoldenGitte, winning tournaments such as NetParty Fyn 2018 and Thunderpick Invitational #3. Later, he joined Tricked Esport, where he claimed gold at the LOOT.BET Hotshot Series Season 2 and the V4 Future Sports Festival - Budapest 2019. Additionally, he earned silver at the Good Game League 2019 and finished 3rd-4th at the Copenhagen Games 2019.
Despite his successes and consistent performances, Rasmus left the team in November 2019 and, by December, joined MAD Lions. With his new team, he continued his winning streak, securing gold at Flashpoint Season 1, silver at Eden Arena: Malta Vibes - Week 9 and Nine to Five #5, and finishing 1st-2nd at Intel Extreme Masters XIV - World Championship: European Open Qualifier #2, DreamHack Open Leipzig 2020: European Qualifier, and Elisa Invitational Fall 2020.
In March 2021, Rasmus joined HEROIC, where he remained until January 2025. During his time with the team, he achieved numerous titles. The most significant include gold medals at PGL Major Antwerp 2022: European RMR A, BLAST Premier: Fall European Showdown 2022, and PGL Major Copenhagen 2024: European Open Qualifier #2, as well as silver medals at Intel Extreme Masters Katowice 2023, BLAST.tv Paris Major 2023: European RMR B, Intel Extreme Masters Rio 2023, Intel Extreme Masters Dallas 2024: European Qualifier, and Thunderpick World Championship 2024.
