The next humble indie bundle has been announced! Penumbra Overture was in the last one, so heads up, Frictional! The first one was how I got to know about penumbra, and now I own everything Frictional has ever released!
Could you send a link to this? I thought it was something else. I read in a recent blog post by Wolfire that you can now activate your original HIB games on the Steam client, but nothing about a second one.
