About Eon Altar
Eon Altar is a local co-op role-playing game for one to four players, set in an original sword-and-sorcery fantasy world. You explore the dungeons and tunnels beneath Tarnum Fortress, take on quests and challenges, and fight the Eon Altar’s many defenders in tactical, turn-based combat. An ancient, malevolent presence stirs below the fortress, and a small band of heroes must try to stop it from consuming the world.
Story and choices
The story unfolds across nine episodic installments. You interact with enemies, allies and other players by acting out your character’s lines, and make choices that shape your hero’s destiny. You can cooperate with your allies or deceive them, using player-to-player dialogue to expose the truth in myths and legends. The game’s story explores friendship and betrayal as the heroes confront the force that brought them together and the challenge of standing up to their gods.
Play together or alone
You can play solo or with up to three friends. Players connect their mobile devices to a central platform to coordinate tactics and movement, while each person controls their character from a smartphone. You receive personalized secret thoughts from your character, can choose whether to share personal information with friends or use it against them, and can upgrade and manage your character without interrupting the others. Context-sensitive information on the phone supports control of the action.
Combat and setting
Tactical battles call for strategy, magic and martial prowess as you face legendary enemies. The game also features atmospheric environments, an original fantasy setting and fully voice-acted NPCs; players voice their own characters. The soundtrack is by composer Tom Salta, known for his work on the Halo series.

Publishers create keys to sell in other shops, which is why a key can cost less than in the official store, and once you activate it the game is yours to keep, just like a store purchase.
