TeaserPlay recently shared on their YouTube channel a new Dark Souls IV concept video that shows how the game would look in Unreal Engine 5. This new concept trailer imagines the game with a Greek culture theme, so some locations look way too bright for the series, but forests and underground locations do have that certain Souls vibe that fans have come to love over the years.
As mentioned above, it is extremely unlikely From Software will go back to the Dark Souls series following Elden Ring’s deserved success. We cannot know what the future holds, however, so, one day, we may really end up playing a new entry in the now-classic series maybe powered by the latest version of the engine by Epic.
