Status Update: Linux and Mac ports

[Urkle]

I would like to buy penumbra for linux. Will it be available as separate buy (non-boxed) or you have to buy win version and then will be some kind of separate linux installer (like with doom3)?

The linux and mac game will be a separate online download purchase only.   You will not be able to purchase the Windows version and run a "linux" binary on it unfortunately.
