Unofficial notes, not affiliated with Games Workshop, Auroch Digital, poncle or Lutris.
The Lutris page for Warhammer Survivors (Warhammer Survivors - Lutris) already offers a GOG auto installer, so most people don’t need a custom script. On Steam it is app 3669620 and runs through Steam/Proton as usual.
One thing worth knowing: hotfix timing can differ by store, so a GOG build may lag or lead the Steam build for a day or so. If a fix mentioned in patch notes is missing, check your store’s build first before blaming Wine.
I keep public source notes on platforms and release timing, as well as Steam Deck notes. They only collect what the developer and stores have published; no Wine/Proton version claims.
If you run the GOG version through Lutris, it would help others if you replied with your runner version and whether anything needed tweaking.
