unknown for steam?

[jo291]

well i do own the retail copies of overture and black plague but i lost the disks seeing as my entire computer room is stuffed with retail boxes. so just a while ago i was thrilled to learn that they were realesed on steam but i decided to wait for the penumbra collecters pack so i went through black plague and overture again and played requiem for the first time [i liked it but i thought it was the worst in the series]


so after playing i was interested to know if unknown was going to be on steam. so is it??? :question:
