Kim 'Shuttle' Yoon-joong has decided to retire in order to complete his military service.
A veteran of six years, he made his decision due to the transition from Brood War to Starcraft II.
Shuttle made his debut for STX Soul in 2007. He is known as the 'Crying Toss' due to breaking down in tears after qualifying for the OSL in 2009.
With Kal leaving for ACE, he became the veteran of the Protoss group on STX. He considered applying for ACE, but with it not accepting any more recruits, he decided he would rather retire and complete his military service normally.
In a closing statement, Shuttle thanked his fans for cheering for him during his career as a progamer.
