On February 14th 2014, IMC Games started recruiting Korean gamers to participate in the Focus Group Test. Korean players can register at the official TreeofSavior.com website.

The Focus Group Test can only be participated by Korean residents. This is because they want native Koreans to provide detailed and precise feedback on Tree of Savior game.

The Focus Group Test was held on Feb 25, Mar 4, Mar 11 and Mar 18. A Closed Beta Testing for international players will begin after the Focus Group Test.
