No Man's Sky won't need PS Plus
Technically, No Man's Sky is a single player game, but Sony's store page stated "online multiplayer also requires a PlayStation Plus subscription." A Hello Games spokesperson told Game Informer that you won't need a subscription, but added, "You will need to connected to the internet for your discoveries to register with the universal atlas."
In other news, Hello Games' Sean Murray took to Twitter to reassure fans that the game doesn't use a patented "superformula." He added, "I wish Johan Gielis, the author, all the best in future. We're going to meet and chat maths once the game is out."
