En Masse Entertainment published the original 2011 PC game, which was developed by Bluehole.
From 6 AM PST on March 9th to March 12th at 12AM PST, console users interested can simply download the client from their storefront and have full access to the test.
Bluehole having their focus on other things now leaves En Masse to take the helm on the console port for TERA, which will likely launch a little behind the PC version in terms of expansion content.
The full game comes out sometime later this spring, but this is likely the only time you’ll get to try out the game before launch.
