Released for the PC early last month and for the Mac in the spring, Spiderweb Software's Blades of Avernum is the fourth title in its award-winning series based on this scenario, which re-visits its earlier Exile property. Described as a role-playing system rather than a game, it encompasses an editor plus a number of pre-made adventures. Among them, A Small Rebellion, charges you to infiltrate and destroy a group of rebel, but also allows you to join them should you so choose. The Valley of Dying Things involves finding the secret to a virulent plague, The Za-Khazi Run has you race down a subterranean river to reinforce a beleaguered fort, and Diplomacy With the Dead requires you to help a remote city deal with a powerful vampire. Recently, Lead Designer and Programmer Jeff Vogel looked back at his latest project.
