Early CS:GO career and Team LDLC
After Counter-Strike: Global Offensive was released in August 2012, Vincent Cervoni Schopenhauer changed his nickname to "Happy" and formed a new team called PRIME in September 2012 with apEX and Maniac. The following month they were picked up by Team eXtensive! which became LDLC.com in January 2013.
Due to poor results LDLC decided to disband their CS:GO team in August 2013. After this Happy formed another mixed team called WE GOT GAME with players such as fxy0 or GMX. They later added kennyS, Maniac, and Uzzziii to the team. This squad was signed by Recursive eSports before the first CS:GO Major sponsored by Valve, DreamHack Winter 2013. At DreamHack, they beat Universal Soldiers and iBUYPOWER on their way to a 2nd-place finish in the group behind Ninjas in Pyjamas (NiP). In the quarter-finals they played Fnatic, who beat them 2-1 and went on to win the tournament.
Due to lack of financial resources, Recursive eSports parted ways with their CS:GO division on 20 January 2014; despite this, players stayed together and created team Nameless. After rumours that Nameless and Clan-Mystik planned to merge their teams, Happy, together with Uzzziii, Maniac, along with KQLY and apEX from Clan-Mystik, joined LDLC in February 2014.
Happy led this team to 1st place in DreamHack Valencia 2014 and a T5 placing in the second CS:GO major, EMS One Katowice, where they were defeated 0-2 by eventual Major champion Virtus.Pro. Happy led LDLC to a T3 placing at the next CS:GO Major, ESL One: Cologne 2014, where they beat Virtus.Pro in the quarterfinals before falling to eventual champion Ninjas in Pyjamas 1-2 after a 14–16 loss on the last map.
At the beginning of September 2014, a few weeks after ESL One: Cologne 2014, three LDLC players, KQLY, apEX and Maniac, left the Happy-led LDLC squad and signed with another leading French CS:GO team, Titan eSports. In response, LDLC released their roster, and Happy formed a short-lived mix team called Mercenary, which contained Shox, NBK, SmithZz and kioShiMa, and was picked up by LDLC after two days.
By late 2014, Happy was the best player on LDLC and one of the top players in the world. Happy became known for his play on the B site on the Counter-terrorist side of the Inferno map. Before the next CS:GO major, LDLC was considered to be the second-best team in the world. At DreamHack Winter in November 2014, Happy led the LDLC squad to victory over Fnatic (who withdrew after using an illegal boost in their quarterfinal round against LDLC), Natus Vincere, and Ninjas in Pyjamas (NIP) in the grand finals. In the grand finals, Happy almost had double the kills of any other player in the first round, and his play carried LDLC from a 13–15 deficit into overtime on the third and final map. For his high level of play, Happy was named tournament MVP. This victory made Happy's LDLC squad the official CS:GO world champions and possibly the best team in the world, given their victory at the major and string of second-place finishes in less important tournaments beforehand.
In January 2015, Happy led LDLC to victory at the MLG Aspen Invitational, the first CS:GO tournament organized by Major League Gaming. Happy had two crucial three-kill rounds against NIP in the first map of the grand finals, a rematch of the previous CS:GO major. Happy was the standout player of the tournament finals and was voted match MVP.
