Arseny "cen9" Trynozhenko, a former well-known Ukrainian esports player, is now a popular streamer and sought-after esports commentator.
Arseny began his professional player career in 2009, competing in Counter-Strike 1.6. In 2012, Trynozhenko transitioned to CS:GO by signing a contract with NaVi. With the team, he reached the finals of the StarLadder StarSeries VI tournament and also took home bronze at TECHLABS Cup 2013.
During his time as a player, cen9 was very active. He wasn’t afraid to take the initiative and often helped his team win what seemed like doomed rounds. However, Arseny's esports career was short-lived, and in 2013 he decided to hang up his mouse. Despite this, he remained within the NaVi organization, covering the team's activities and successes.
After retiring from professional play, Arseny also tried his hand as a coach for pro100, but soon gave up on coaching and decided to fully dedicate himself to streaming. He launched his first broadcast in 2015, with the proceeds being donated to charity for a children's home.
