As we have previously announced, new versions of Vagrus' free Demo is going to be published to GOG.com in the next couple of days or so (perhaps it is already out as you are reading this). You will probably be pleased to know that this incarnation of the Demo will have a small set of achievements you can complete!
The Demo exist on GOG as a separate application called Vagrus - The Riven Realms: Prologue, you can find it through the link below.
The Steam versions (coming a bit later) will include DRM protection (the player has to have Steam running to play) while the GOG.com build is DRM free, as per GOG's model.
On both platforms, the Demo will be available for Windows, macOS, and Linux. Note that GOG.com does not support achievements for Linux builds at the moment, so you will not be able to unlock them with that build for now.
