Today I have some news for all you Mac OS users out there. First of all Kreator fixed the OS X packages which initially had a little bug related to the PhysicsFS library preventing the game from starting.
So if you suffer from this bug, just head to the Download page and re-download the OS X package.
And last but not least: DXX-Rebirth v0.56 now is available for Mac OS 9, too. Have much fun with it!
