Gameforge and En Masse Entertainment have announced that both the NA and EU versions of TERA are now free to play as of Tuesday, February 5th. Players will need to download a patched version of the game to access the F2P options.
From the TERA Rising NA release:
In-game content launching today includes an all-new wave-based dungeon and a PvP battleground map. The multi-level Crucible of Flame dungeon will challenge players with a series of epic, high-level battles, and PvP players can jump into an all-new three vs. three battle arena. Two new game servers, one PvE and one PvP, also launch today to give players the option of joining a fresh server or one with an existing community.
