The game is close to the Polish people (and store), so it’s not surprising to see it offered for free on GOG.
The Witcher 3: Wild Hunt Concert on GOG is a film from a concert that features the melodies of CD Projekt RED‘s base game, as well as from the Hearts of Stone, and Blood and Wine expansions. We’re talking about a live performance, complete with a choral and orchestral take on the soundtrack, offered for free by GOG!
Until November 12, 6 PM Eastern, The Witcher 3: Wild Hunt Concert can be downloaded in four different formats, ranging in size from 675 MB to 19 GB – the roughly 1.5-hour recording is an excellent gift from the Polish, DRM-free game store.
The recording will not be in your library – you’ll have to access it by picking the Movies tab from the drop-down profile menu on GOG’s main page. Via the GOG Galaxy client, The Witcher 3: Wild Hunt Concert might not be available.
Thank you for the freebie, GOG!
