The tickets for ESL One Cologne 2018 have already been sold out. The tournament is one of the most well known and famous tournaments in Counter-Strike. It helped develop ESL in its early days and create the behemoth that ESL is right now.
The Cathedral of Counter-Strike is filling up quickly. Looks like we will be sold out early again for #ESLOne Cologne. Can't wait to see the crowd take their seats on July 6.
