EG-Liquid was a partnership between the teams Evil Geniuses and Team Liquid. The two teams formed a combined roster of players in order to compete in Proleague. The partnership was announced on December 4, 2012.
EG-Liquid made their debut as the first foreign team to compete in Proleague on December 8, 2012. Their first match was against KT Rolster, which resulted in a 0-4 loss for EG-Liquid. For this match, EG-Liquid had to play without TaeJa, HerO, and Stephano. EG-Liquid scored their first win in Proleague in Week 2 with a 4-0 win against Samsung Khan. By the end of Round 1, EG-Liquid ended up 4th overall, with a record of 3-4.
Round 2 marked the debut of Stephano in Proleague. During Week 1, EG-Liquid was all-killed by KT Rolster’s Flash, but managed to beat SKT T1 4-2. Week 2 was Stephano’s first appearance in Proleague, in the matchup versus CJ Entus. After being down 1-2, Stephano was picked to play against CJ’s herO. During the start of the match, Stephano typed “gl, hf” and was given a warning by the KeSPA referees. Stephano won 2 games for EG-Liquid before falling to Hydra, with EG-Liquid ultimately losing 3-4 to CJ Entus. Round 2 ended with EG-Liquid going 3-4, with an overall score of 6-8 for the entire season.
By Round 3, the EG-Liquid hype had died down after 2 losing rounds. The beginning of Round 3 was no improvement, with 4-1 losses to STX SouL and Samsung KHAN. EG-Liquid’s lack of Proleague experience showed, with a 1-6 record in Round 3 and a 7-14 overall record for the season. This poor performance put EG-Liquid in last place, behind Team 8
After the poor performance in Round 3, EG-Liquid announced on March 13 that they would be adding former SKT Coach Park Yong Woon as the new head coach. After releasing PuMa, EG picked up both aLive and Oz, reaffirming their commitment to a focus on Proleague.
