Aika players are getting a new zone, a level cap increase (to 75), new mounts, and a few choice pre-launch bonus events. These include triple (yes, triple) XP and play-for-rewards summer events which offer a laundry list of cool prizes just for logging in. As for the new zone, Traband was formerly a temperate and beautiful island but is now a frozen wasteland "where only the most bloodthirsty beasts survive." That's OK, though, because what self-respecting MMO adventurer wants to hang out in a tropical safe zone bereft of killable monsters?
The Aika website has more details on Epic II, and you'll also find the client download front and center on the new splash page.
