No Man's Sky's stupefying infinite universe is available on PS4 and PC, but to explore all of it's sky you would have to born thousand times again. No Man's Sky is a game about exploration and survival, set in an unending universe.
You can fly over mountains even on planets, there is no limitation. You can fly easily from the surface of a planet to another, and even you can reach up-to the sun, what matter is your stamina, how fast you'll make your way through this universe is up to you.
A game without risky part is boring, every solar system, planet and ocean is not only rolling in wonder but with danger and the best part is you are vulnerable.Your ship is sailing lonely in the universe and every experience can test your skills to the limit. In No Man's Sky every success and every defeat has everlasting experiences.
