"We've noticed there's some confusion about the Steam version of the game versus the other versions like the one that'll be distributed through gog.com or the vault.
The short of it is that all versions all equal and all versions are compatible with one another.
You do need a Steam account if you want to take advantage of all of the Steamworks features that are integrated into the game.
If you don't have a Steam account, then you can still play online or in a LAN, but you won't be able to use the Steamworks features. In that case the Steamworks part of the game will become grayed out.
All versions are DRM free btw but feature a secret surprise for pirates.
Hope that clears it up."
Does this mean that if I bought the game on GoG and have a steam account there is a way for me to transfer the game to my steam library and use the steamworks? If yes what is the procedure needed to do so please?
