Hello Games' Sean Murray took to the PlayStation stage tonight for an extended demo of No Man's Sky. He showed a brief space battle, then zoomed out to the expansive universe to show just how many star systems there are. He picked one at random and went to it, then found a beacon to explore. On the planet's surface, he saw a Sentinel that's meant to protect planets from explorers like him. Finally, he shared some data on the planet's beacon, and ended the demo.
