Yes, we're happy to tell you that Killing Floor is now on its way into the Steam Linux Beta. For those of you wanting to try it out, if you aren't already in the Linux Beta, we hear they will be expanding it soon. We'll be rolling Killing Floor out fully when Steam goes live with the Linux Client. And we will be adding Red Orchestra: Ostfront 41-45 (and the Mac version, too) and Dwarfs!? if all goes to plan, as well!
For those with access to the Steam beta, we'd like to hear your feedback, bugs, issues or anything else.
