After being in closed beta to work out the kinks, Nexxon has announced that MapleStory Adventures — the Facebook spin-off of MapleStory — will be launching on the social network later today.

The game will officially be in open beta starting at 4PM Pacific (7PM Eastern) tonight. The Facebook iteration will be similar to the incredibly popular web-based version, but with a number of changes to make it better suited for a social network. For more details on what to expect check out our hands-on preview from when the game was still in closed beta and check out the debut trailer for the game below.
