Geneforge 4 - Released for Mac

Spiderweb has released Geneforge 4: Rebellion for the Mac, with the PC version to follow in early 2007.  As always, there's a demo on the game's page:

Geneforge 4: Rebellion is now available for the Macintosh! The Geneforge saga continues, as a vicious war engulfs the lands of Terrestia. Choose whether to aid the rebels or their former masters, choose from many possible paths to victory, and, as always, command an army of totally obedient mutant monsters.

There's also a v1.01 patch available.
