The Merlin Twitter account has been teasing a mysterious reveal, and now we’ve got the answer: an online game to be played on Facebook!

Although the official reveal isn’t happening until tomorrow, SFX can report that what the Twitter account has been hinting at is in fact a Facebook game, created by Bossa Studios.

Merlin: The Game will launch in August, but a beta version will launch during next month’s San Diego Comic-Con.

The game will allow people to explore the world of the show, and to unite with characters like Merlin or Arthur (perhaps suggesting that you won’t play as any of the known characters?).

You can sign up for the beta trial at the official Merlin the Game website for a chance to try out the game early! Do you like the concept art for Merlin and Arthur?
