At IEM Season VII - Global Challenge Cologne, the team went undefeated in their group and bested the Korean lineup consisting of players that took 2nd at the Season 2 Championship, CJ Entus. However, they were unable to beat the other Korean team, SK Telecom T1, in the finals, placing 2nd in the tournament.

With the North American and European community extremely excited for the amped up events of LCS, Season 3 began with Riot's new league, a 10 week series with the continent's best teams playing against one another. Fnatic became the most consistently powerful team throughout the series, with solid jungle play and pressure from Cyanide. the team ended the 10 weeks on top, with an intimidating record of 22-6. Cyanide and his comrades had automatically reclaimed their spot in the league for the summer split, when going into the Season 3 EU Spring Playoffs.

The start of the Summer Split was shaky for Cyanide and the team. Fnatic could not break into the top 2 until Week 7 of the split, at which point their main rivals Alliance were already a considerable distance ahead of them, in the race for 1st place. Despite Cyanide's impressive displays on Elise and now also Evelynn, Fnatic could only manage a 2nd place finish. The team aimed to put the split behind them and focus on the Summer Playoffs. A close fought win over ROCCAT in the semifinal meant that Cyanide and the team would face Alliance in the final. The match ended in defeat for Fnatic, but the playoffs saw the team seal their qualification for the 2014 Season World Championship.
The World Championship saw Fnatic placed in Group C with Samsung Blue, OMG, and LMQ. The team were only able to win 2 matches out of 6 in their group, meaning that they would go no further in the tournament.
