This article is for our legacy TERA launcher. We encourage you to upgrade to our new En Masse launcher to enjoy faster downloads, patching, and a better overall experience. The legacy TERA launcher will continue to be usable, for now. We'll eventually halt support, once we've confirmed the new launcher works as intended for all players.
