You can grab the Dark and Darker $30 premium upgrade for free right now, but you’ve got to be incredibly fast. Developer Ironmace added a free version of the extraction game earlier this year, and now in collaboration with the Epic Games Store, you can grab the permanent premium upgrade entirely for free. There’s a catch though, and it’s a pretty big one, as you’ve now got less than 24 hours to claim the upgrade before the offer disappears.
