Nordic Games executive producer Reinhard Pollice revealed on a Steamthat Darksiders 2: Deathinitive Edition is the developer's vector into getting a Darksiders 3 game made.
"Darksiders 2 Deathinitive Edition was just the start," Pollice wrote, "Since we acquired the franchise we were looking for options for doing a DS3. The remaster was just a way to get some spotlight on the franchise again, reactivate the community and have a better starting position for DS3."
He went on to write that the Deathinitive Edition was "a natural choice" to bring it to the current gen of consoles, and the PC release was so that the developer could "give it to everybody who spent money on the same content before for free." It was only completely free, however, for those who bought the Darksiders Franchise Pack. Those who just bought Darksiders II got an 80% discount on the Deathinitive Edition.
Nordic Games is comprised mostly of staff who worked at Virgil Games, the developer who produced both Darksider games.
