Rise of Immortals Producer's Letter

Greetings Immortals!

Since April 5th we've brought several waves of thousands of players into the closed beta of Rise of Immortals. The beta testers are helping us balance the current Immortals, play matches on all the available maps up to 5v5 players, socialize in the hub, try out the just-released persistence features, and more!

And that's just to warm things up. We have three more Immortals being added to the closed beta next week that we'll share with the public soon after, not to mention Ichorr soon after that you saw recently. We have Immortals that spawn poisonous pets, shoot lightning from their spider-like fingers, know martial arts, and like Pyschozen, can bend your mind into a pretzel of confusion...

We feel that Rise of Immortals is coming onto the stage with more than your average MOBA has to offer. There's all the unique competitive features mentioned above, and more we're working on. And I'm not even getting into all the community requests your community manager, Mathew "Berek" Anderson, has listed for the designers.

When you first check out the game, you will be entering a core MOBA experience first and then on top of that you get all the goodies described above. This game is designed for the community, and while we may not ultimately be able to add CareBorg's sister, CareBetty, we'll do what we can.

But I won't continue to bore you with a feature list... we've been in closed beta for a couple of weeks now with plenty more to talk about, especially as open beta and release approach. If you haven't registered for the beta yet, visit www.riseofimmortals.com and sign up! While you wait, visit the forums and tell us what you think about the currently released videos, screenshots, and other game previews.

Speaking of previews, we plan to release another Petrocast next week, more sneak peeks of the next three Immortals, and of course a stocking full of beta keys! There's so much to share with you, we need your help in deciding what you want to see. Let us know!
