Additionally, Kotaku's Jason Schreier - who initially broke the story of the delay - received threats as well.
Death threats have become increasingly common in the gaming world, and have been received by entities like Valve, Sony, and the Game Developer's Choice Awards.
No Man's Sky's enormous, procedurally generated universe and planet-hopping gameplay have sparked great enthusiasm amongst gamers since its reveal in 2013.
"I think people really like the concept, but it's very important for me to deliver on that," said Murray during a recent trip to Los Angeles to show off No Man's Sky.
"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.
"It's not like a typical video game," said Murray. "You don't start off in prison, then someone throws you a gun and you have to rescue your dad or something.
"It's about finding these places and becoming more engrossed in them."
