Blue Hole Studio has announced that phase 3 of the TERA closed beta test is now underway! The test will run from today, February 26th, through to March 7th, and will expand the testing pool to 20,000 testers.

Closed Beta #3 will include many new additions and changes as well, such as: an expansion of the available game world for players to explore, 68 additional skills, swimming, climbing, and jumping actions, in-game voice chat, new dungeon instances, a party search feature, and an auction house.

Six tribes, eight classes, and 88 character models will also be available as part of this latest beta phase.

A number of details are also available regarding the upcoming Open Beta phase, which is said to include a skill enhancement system, large scale PvP battlefields, PvP rewards, potentially a political system where high-ranked players can strive to become a leader along the same vein what is currently implemented in Webzen's ArchLord, mounts,  and more.

It's important to note that these details are for the Korean beta test phases. No details are currently available on the Western version's beta test, though the game is slated to arrive in the West sometime in early 2011.
