Mouz

MOUZ, originally called mousesports, is a German esports organization. It competes in multiple games, with its Counter-Strike 2 team being the most famous. MOUZ was a founding member of the G7 Teams.

The organization started in 2002 in Berlin as a Counter-Strike squad. It began in small tournaments and gradually moved to bigger events. By 2006, when the G7 Teams formed, mousesports was one of Europe’s top gaming organizations, with divisions in Counter-Strike, Warcraft III, Quake 4, Battlefield 1942, and Unreal Tournament.

In May 2007, mousesports bought Nihilum, the leading World of Warcraft guild worldwide, making it a subsidiary called "Nihilum: mousesports MMO." Nihilum was the organization’s strongest team in European competition. But by fall 2008, the relationship became uncertain, and in November, the former PvE team of SK Gaming merged with Nihilum’s players, ending the partnership after over a year and a half. Mousesports kept the Nihilum brand and launched a new community website in August 2009, linking the World of Warcraft guild Method, the WotLK Wiki, and Nihilum under one domain.

In April 2009, mousesports dropped its Defense of the Ancients team, despite its success. In early 2010, it added a star-studded StarCraft: Brood War roster with players from the US, Canada, Germany, Poland, and Ukraine. The team later shifted fully to StarCraft II during the Wings of Liberty beta and became well-known.

A major tragedy struck in July 2010 when Counter-Strike player Antonio "cyx" Daniloski died in a car accident caused by a tire failure, after missing a flight to China for a tournament. The organization held memorials and tributes, with a permanent dedication on its website. Months later, the remaining Counter-Strike players—Fatih "gob b" Dayik, Navid "Kapio" Javadi, and stand-in Christian "Blizzard" Chmiel—retired after the ESL Pro Series Season XVII Finals.

In March 2012, mousesports ended support for its Counter-Strike division, citing a lack of market due to the rise of Dota 2 and League of Legends. It picked up a new Counter-Strike: Global Offensive roster later that year.

In April 2017, mousesports signed the former Dota 2 team Ad Finem, returning to that game after nearly two years. In August, Christian 'loWel' Garcia was released, replaced by Miikka 'suNny' Kemppi, and Denis 'denis' Howell was released, replaced by Martin 'STYKO' Styk. The Dota 2 team disbanded in December 2017.

In March 2018, mousesports signed its first full Tom Clancy's Rainbow Six Siege roster. In June, it acquired Janusz "Snax" Pogorzelski from Virtus.pro to replace the benched Martin "STYKO" Styk. In July, it picked up a Rocket League team of Tigreee, Alex161, and Skyline, who began RLCS Season 6. In October, STYKO returned to the starting lineup. In November, the Rainbow Six Siege coach announced the team was dropped.

In January 2019, Linus "al0t" Möllergren joined from compLexity Gaming, replacing Skyline. In February, mousesports signed a second Rainbow Six Siege team, the former ENCE roster, with coach Michiel "oVie" van Dartel, but dropped them in July. In March, the roster was revamped with the additions of woxic, frozen, and karrigan, while oskar was released and suNny and STYKO were benched.

In June 2020, mousesports left competitive Rocket League and released its roster. In March 2024, MOUZ returned to Dota 2 by upsetting The International 2023 champions Team Spirit in the 1win Series Dota 2 Spring group stage. In December 2024, MOUZ withdrew from League of Legends, having recently competed in the ESL Pro Series and formerly in the European Challenger Series.

In a quarter-final at the Blast Austin Major 2025 on June 19, 2025, MOUZ eliminated defending Major champions Team Spirit with a 2–1 win, advancing to the semi-finals.
