Two of Uncharted's best characters will star in this brand-new adventure.

Uncharted 4 may prove to be the final adventure of Nathan Drake, but if you think that Naughty Dog is done exploring everything that the world of Uncharted has to offer, you ain't seen the debut trailer for Uncharted: The Lost Legacyyet.
Given how adamant Naughty Dog seemed to be regarding Uncharted 4's place as the finale of the Uncharted franchise, the reveal of Uncharted: The Lost Legacy came as a huge surprise when it opened this year's PSX event.
True to their word, though, Naughty Dog is not basing this game around series protagonist Nathan Drake, but rather two of the franchise's best side characters. The Lost Legacy will follow Uncharted 2's Chloe Frazier and Uncharted 4's Nadine Ross as they set off on an adventure involving the...well, that part isn't entirely clear as of yet. The trailer shows Chloe sneaking through a war-torn town in disguise before meeting her accomplice Nadine atop a roof, and the video's description makes a vague reference to a "fabled ancient Indian artifact" that the two are trying to recover.
What is clear is that this title will play out similar to the Uncharted games we've come to know and love. It's worth noting that this preview seems to downplay gunfights and emphasize stealth and hand-to-hand combat, but the gameplay revealed thus far retains that signature style of cinematic excellence that only Unchartedcan properly provide.
Much like The Last of Us Part II, there's no word yet on when this game will be released. This might be interpreted as good news by those who have not yet purchased a PlayStatio yet and suddenly feel the urge to start saving up.
