A developer using the name MegalomaniacNG, a.k.a. Reinhard Pollice, Executive Producer at Nordic Games, has responded to a Steam thread calling for Darksiders 3 and it looks like the game may be on the way.
“Darksiders 2 Deathinitive Edition was just the start. Since we acquired the franchise we were looking for options for doing a DS3 [Darksiders 3]. 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.”
Presumably the remaster will help fund some of the development costs of Darksiders III, although Nordic games have yet to make any official announcement about a third game in the series.
Darksiders 2: Deathinitive Edition is out now for PC, Xbox One and PlayStation 4.
