The Irish video game developer Brendan Greene, better known as PlayerUnknown, left active development on PUBG: Battlegrounds back at the end of the last decade to set up PUBG Special Projects and PlayerUnknown Productions. And now we’re getting a glimpse of what he’s been working on.

PlayerUnknown Productions has released Preface: Undiscovered World, a free tech demo of the Melba engine’s power to create new planets. This comes after Unreal Engine could have been bettered for realism by the new Dagor Engine by Gaijin Entertainment, designed for first-person shooters.
