It's long been "known" that Killing Floor was coming to Mac. And by "known" I mean that it was shown off in a desktop thread at the Tripwire forums from one of the game's developers. Nothing was announced but it seemed like it would only be a matter of time before an official statement was made.
Big Download has confirmed with Tripwire Interactive's John Gibson that a Mac version of both Killing Floor and Red Orchestra: Ostfront 41-45 are coming. Support for the previously released PC DLC is included, as well as Steam achievements, and cross-platform multiplayer. A specific release isn't set but the studio hopes to have a release ready around the same time the Steam client is released on the Mac OS X on May 12th.
