Paradox Interactive announces they will launch the Penumbra Collection for Linux and Mac tomorrow, which bundles Penumbra: Overture, Penumbra: Black Plague and the Penumbra: Requiem expansion. The bundle will include a brand new installer which "will improve the user experience compared to the original 'three downloads with three serials' installation procedure." The package will launch at a discounted $5.00 price, which will return to $20.00 at the conclusion of the launch weekend. Thanks Gamer's Hell.
