A tl;dr of our article found here.
OBT Service will open on April 22 @ 12PM PST / 3PM EST
You can find the Tales Runner client on our OGPlanet Launcher (http://www.ogplanet.com/download.og). Alternatively, you can download the game client from our mirror site (http://download.cnet.com/Tales-Runner/3000-7540_4-10914806.html)
it is recommended to download the game ASAP before the opening of the server since the update patch is much shorter! To anyone that is having issues with downloading through the OG Planet Launcher, the mirror site works as an alternative! Considering that there is 1 DAY until Second Beta starts, it is recommended to download the game now or anytime soon so that you can jump into the game faster! See you in game Runners!
