Stardiver

Stardiver is a sci-fi, single-player, action-adventure game where you pilot a ship, fight enemies, and slay Bosses. The game takes place entirely underwater. Stardiver will take you to an unknown world in which you’ll experience exciting fights, and discover new species and places. And you’ll take care of resources supply, crafting items in your base, and developing your own ship.

You become a pilot, explorer, scientist, and judge responsible for the planet's fate. The plot guides you through series of mysteries, leading to the revelation that the mastermind behind all events affecting you and the planet's environment is Artificial Intelligence. Determining whether it is inherently good or bad depends on the perspective you choose to adopt. Ultimately, the decision must be made by you at the conclusion.
