Avadon 2: The Corruption, the second game in Spiderweb Software's Avadon trilogy, has been released and is now available for both Windows and Mac OS computers. It can be purchased from Steam, GOG.com, the Macintosh App Store, or directly from Spiderweb Software's own website. A demo is available for anyone who wants to try it before they buy it. Spiderweb Software intends to release the game on the iPad sometime in the future, though it doesn't yet have a specific date for that.
Avadon 2 is a traditional isometric RPG with tactical turn-based combat. It is set sometime after Avadon: The Black Fortress, and continues the story of the titular fortress. You play as a new hero who has been conscripted by the fortress of Avadon after it has been damaged in a sneak attack, and must choose to either rebuild the fortress and all it stands for or betray it and find a different path.
