The sequel to 2011's Avadon: The Black Fortress will be the second game in a planned Avadon trilogy as players return to the rich fantasy world that has been thrown into a civil war.
Avadon 2: The Corruption will feature five classes for players to select, each with dozens skills and spells to unlock for each.
It will also offer a branching story with choices that can lead to multiple endings along the way.
It is being developed by Spiderweb Software, which is known for role-playing games with complex plots, high-quality writing, tactical combat and late '90s PC graphics.
Avadon 2: The Corruption will be available later this year on PC, Mac and iOS.
