Update #15 - Are you Ready for Giving?

Welcome to Update #15! As usual, while we've been busy with Episode 3, we've also been busy building new features and making Eon Altar better for our existing and new players!

Just in time for the holidays, you can now give items and resources to your friends in-game! While some items are unique to a given character and cannot be traded away, most items can. And you can now trade in the combat arenas, as well. So give the gift of healing and hand over those Vials of Copperweed!

You can also now finally start a game without hitting the Start button on the computer! Once you're in a campaign and everyone has joined, everyone can hit "Ready" on their own controller and the game will boot up in 5 seconds!.

In other features, the game's been tracking your player-to-player relationships this whole time quietly, but we haven't been showing this information to players...until now! When you're in a player-to-player dialogue, you can now see the effects of certain dialogue options on your relationship, and you can see the totals in your Stats screen in the controller app. Right now these values don't do anything, but come Episode 3 they might just have an effect.

Finally, Free Run. Boy, that's been a bit of a neglected feature. We basically implemented it early on in our development cycle and haven't changed it since, and, well, it shows. It's been a little rough around the edges, and by rough I mean it would...stop on edges. No longer! Now, Free Run will run around narrow objects and not be as pedantic when you're running near walls. It should feel a lot better when free running around now! I mean, it'll still feel like you're driving a land boat, but at least now it's a land boat with some smarts about moving around things.

Some of the other notable changes are as follows:

  • Potion of Mastery is now in the game! Congratulations to Oleg Trylis on his winning Crafting Challenge entry!
  • We now correctly store your choice about the fate of a certain someone at the end of The Wolf of Yriel such that Together We Fall actually makes sense.
  • A Special Thanks to MaxLimitz in the credits for all the help he's continually given us over the past few months. You've been amazing!

We're really excited to announce the final Episode of Season 1, The Watcher in the Dark, will be coming January 19th. In just over a month you'll be following up on the exciting finale of Episode 2:

More story, more enemies, more "accidentally" fireballing your friends!

Spoiler Alert for those who haven't completed Episode 2:
After the defeat of Lady Allevia and putting an end to her centuries-old torment, a mysterious, powerful figure has saved you from Guild Lord Davian's attack and left you in the dark caves below the Catacombs. Ancient ruins lost to history, a malevolent race, and this mysterious figure's agenda all stand between you and Davian: survival isn't enough; your destiny awaits.

Check out the Episode 3 store page on Steam to follow and to add it to your wishlist.

So order the pizza, soda, and/or beer, hop on the couch with your friends, and get ready for the deepest, darkest dungeon crawl yet!

“Eon Altar is an interesting, innovative, and modern spin on the idea of pen and paper RPGs, but using the advantage of a digital medium. It's a hybrid of both, a combination, arguably the best of both worlds.”
TotalBiscuit, The Cynical Brit

“Overall, there’s a really great story being told with Eon Altar, and it’s told in an creative and interactive way.”
Brash Games

“Purchase it, play it, and see how multiplayer RPG's should be made these days.”
