The Pathless Gian Squid, who developed the action-adventure game ABZU, announced Sword of the Sea:
Here is a part of the description of the project from the official site:
“Journey through the surreal undulating landscapes of the Necropolis to discover the lost ocean teeming with life in Sword of the Sea.
Ride your board through seas of sand like waves, gaining speed and catching air as you explore the skatepark-like ruins lost in the tides of the Necropolis of the Gods.”
Sword of the Sea will be available on PlayStation 5 and PC. Release date unknown.
