The third closed beta test for Riders of Icarus is starting soon, so be sure to head over to their site and sign up for a chance to join their final closed beta test and play before (almost) anyone else! Players who participated in the previous phases of the closed beta will not have to sign up again — you can play as soon as the closed beta goes live June 2nd!
Participation in the closed beta also comes with an exclusive, permanent cape reward! Further, the NDA for Riders of Icarus will be lifted for the 3rd closed beta phase. More info on these things and more here.
