Uncharted 4 Gameplay Walkthrough Part 1 E3 2014-2015 Demo Let's Play Playthrough HD - YouTube.MP4

On November 14, 2013, Naughty Dog released a teaser trailer for a new Uncharted game, saying that it will be released for the PlayStation 4. The trailer featured voice over by Todd Stashwick, who was to play Sam, Nathan Drake's older brother, in the game. The trailer shows an ancient map of the African continent while the voice over can be heard. The map stops at Madagascar and Île Sainte-Marie is marked, which was part of Francis Drake's travel route. A Latin sentence is written next to the drawing of a skull: Hodie mecum eris in paradiso (which translates to "Today shalt thou be with me in paradise"), a quote from the Book of Luke 23:43.

In March 2014, it was announced that Amy Hennig, the series writer and creative director, and Justin Richmond, the game director of Uncharted 3: Drake's Deception and Uncharted 4: A Thief's End at the time, had both left the studio, joining Visceral Games and Riot Games, respectively. In April 2014, Todd Stashwick, who voiced the narrator in the teaser trailer and was set to play Sam in the game, was announced to no longer be involved in the game, with the role being recast.
In June 2014, Naughty Dog co-president Evan Wells revealed that game directors for The Last of Us, Neil Druckmann and Bruce Straley, were now leading the project in Hennig's absence. As a result, many of the story elements and eight months of shooting were scrapped and abandoned. At the Sony E3 2014 press conference in June 2014, the title of the game was revealed to be Uncharted 4: A Thief's End along with a 2015 release window. On December 6, 2014, a gameplay demo of Uncharted 4 was shown as the initial presentation of the PlayStation Experience. Troy Baker later confirmed via Twitter that he had voiced Drake's older brother Sam, who appeared in the demo opposite Nathan Drake.

On June 16, 2015, a new demo was showcased at the end of Sony's E3 Press Conference. The demo featured a much bigger environment, large amounts of destruction, new combat moves, and the return of Nathan Drake's mentor, Victor Sullivan. An extended trailer at an E3 press briefing also revealed the return of Nathan's wife Elena Fisher.On July 8, 2015, it was announced that Robin Atkin Downes would be involved in the game. While Naughty Dog originally targeted a rate of 60 frames per second for the whole game, it was announced that a 30 frames per second rate is now being targeted for the campaign, while 60 frames per second is still being targeted for the multiplayer modes. Naughty Dog previously expressed difficulties in getting the game to reach 60 frames per second, but at some point explained that they'd drop the idea if it compromised the player's experience of playing the game. During The Game Awards 2015, a new character, Nadine Ross (voiced and motion captured by Laura Bailey), was revealed. At PlayStation Experience 2015, a new video which reveals a dialog tree was shown.

While the multiplayer was limited to a resolution of 900p, the campaign remains at a full 1080p.
