Spiderweb Software announces Avernum VI, the next installment in their multiplatform RPG series, saying the Mac edition is due this winter and the Windows edition is due next spring. This page has details and screenshots, and here's an excerpt:

The epic conclusion of the award-winning Avernum series. Travel into the strange subterranean land of Avernum, full of dungeons, labyrinths, and constant warfare. A final set of disasters threatens to destroy your homeland in a spasm of famine and warfare. Only you can help your people to get to safety before everything falls apart.

As you wander the gigantic world of Avernum, you will experience:

      • An enormous world. Hundreds of quests, dozens of dungeons and enemy fortresses, and multitudes of characters.
      • A fascinating storyline, full of surprises, treachery, and epic battles.
      • Many unique encounters. Not just mindless hack and slash. Many unusual enemies that will require clever tactics to defeat.
      • Rich game system with over 50 spells and battle disciplines, many character building options, and powerful secret skills to unlock.
      • Unique game world. Unique races and settings make Avernum different from any RPG out there.
      • Experience with previous Avernum games is completely unnecessary to enjoy Avernum 6.
