The Last of Us launches on June 14, simultaneously on Blu-ray and as a download through PSN. Those who choose the latter route on PS3 will find the game playable once the download has reached 50 percent, Naughty Dog creative director Neil Druckmann has told Game Informer.
It's our first taste of PS4-esque functionality, just on the PS3 – as you'll recall, one of the major features touted by Sony is the ability to play games as they're downloaded. This is accomplished on the PS4 through the use of hardware dedicated to background downloading and processing.
Update: This is in regards to the PS3. We've added more clear language to that effect.
