Joe Danger developer Hello Games has revealed its upcoming first-person sci-fi action adventure No Man's Sky.

Based on the trailer revealed at VGX, you switch between walking on land, swimming, and most excitingly, flying - both in the planet's atmosphere and in outer space via various types of ships. You can even blow holes in asteroids then zoom through them, like a boss. And don't forget the giant sandworms, because they're there too.

Made by only four people, No Man's Sky looks insanely ambitious. The planets will have their own ecology and ecosystem, according to Hello Games' Sean Murray, who noted "We're all playing in the same universe." So the stars you see in the sky are actually other planets that other players are playing on. Madness!
