GamersFirst is out of the Sword 2 business, it seems. The publisher announced that it will be dropping its contract to publish and host the title at the end of the year. Fans of the game have no reason to fret that they're about to lose their world, however; HanbitSoft's subsidiary T3Fun will take up the slack come January 1st.
Due to the transfer between companies, players will need to expressly consent to allow their game data to be transferred over. The announcement post contains instructions how to do just that. Also, Sword 2 players won't be able to transfer their GamersFirst store currency, so spending it now is highly recommended.
There are a lot of details to go over, so if this affects you, be sure to read the whole post very carefully.
