Matrix Games Forums

Hi - I have CMANO on Steam. I bought Silent Service and Shifting sands directly from Matrix because I had a coupon. I want to add them as DLC to my Steam install. Neither products seem to have Steam keys available so any advice to a newbie on how to add them to my Steam version of the core game would be gratefully received

melmoth2, license keys from both DLCs are possible to use as a steam keys for their registering in to the steam library.

Perfect! Thank you
