I noticed there is constant updates for this game which is awesome but when can we expect them to be released via something other then the "optional" galaxy client?

We asked GoG and they said that they had some technical difficulties on their side but that updater is automatic and should be available later today. And I'm talking about offline updater. :)

I hope this helps! :)

There is no update flag, but the installer changed from 1.000 to 1.020
