Abzu - PS4 (Pre-owned)

The game is a stylised swimming simulator, with an emphasis on exploring peaceful human interactions with aquatic animals. A simulation of, and interaction with shoaling behaviours of fish is incorporated into the game; predatory behaviours between fish are also modelled. The game is expected to incorporate some elements from typical "role playing games" such as upgrades to equipment.[5] The progression through the game is linear, not an open world sandbox, though the environments are designed to be explored; individual acts of the game are set in different areas of the sea, including caverns, deep oceanic areas, coral reefs and flooded ruins.[6]
