As expected, Uncharted: The Lost Legacy made an appearance during Sony's E3 2017 presser, though it was quite as comprehensive as many were hoping. Naughty Dog actually brought a playable demo of the game to the show floor that those who didn't attend the show weren't able to see. This is going to be rectified in a livestream that will go down next week on June 20th, as Naughty Dog will show off the gameplay demo from the PlayStation booth.
The stream will start at 10:00 am PT/1:00 pm ET/7:00 pm CET on Twitch.tv/NaughtyDog and feature appearances from Creative Director, Shaun Escayg, and Game Director, Kurt Margenau who will also be answering fan questions.
On top of that, Naughty Dog will also reveal the new DLC update for Uncharted 4: Multiplayer and Survival, which will launch on the day of the stream. Uncharted: The Lost Legacy releases on PS4 on August 22nd, 2017.
