'No Man's Sky' reaching to infinity and beyond on June 21

LOS ANGELES (AP) — "No Man's Sky" creator Sean Murray wants everyone in the world to know that his galaxy simulator isn't merely a ridiculously ambitious idea that's wowed crowds at the Electronic Entertainment Expo.

While the virtual environments in most games are meticulously crafted by artists and designers, "No Man's Sky" transports players to a fictional sci-fi galaxy populated by an almost infinite number of planets — each with their own ecology — that are generated by a PlayStation 4 or PC using mathematical rules devised by Murray and his Guildford, England-based indie studio.

"When we set out to make the game, we wanted people to have this emotion, like they're landing on a planet and feeling like no one has ever been there before," said the lanky Irish-born, Australian-raised developer as he demonstrated the game with an almost permanent grin.

With its breathtaking vastness, colorful art style recalling classic sci-fi novel covers and moody score provided by electronic-rock band 65daysofstatic, "No Man's Sky" captured the gaming industry's attention in 2014 when it was first teased at the Spike Video Game Awards and E3.

There's an intergalactic force called Sentinels who will sometimes hunt down players who cause too much mayhem, such as breaking into alien factories to steal blueprints or killing too many dinosaur-like creatures.

The landmark is illustrated on the game's galactic map by a bright light that can be glimpsed past an array of tiny dots, which each represent different solar systems.
