The first game in the action-adventure third-person shooter platform video game series was released a whopping 10 years ago, and to celebrate reaching the impressive milestone, developers Naughty Dog and publishers Sony have teamed up to bring exclusive free items to its PlayStation 4 players.

The items up for grabs include a special 10th anniversary avatar and theme, a remastered dynamic theme from 'Uncharted 2: Among Thieves', and a handful of goodies from 'Uncharted 4: A Thief's End', including three dynamic themes, one standard theme, and an avatar pack.

If that wasn't enough, there's a bundle of multiplayer skins being offered for free in 'Uncharted 4: A Thief's End', whilst 'Uncharted' Point and Relic items are half price.

The items are available on PlayStation 4 until December 19.

'Uncharted: Drake's Fortune' was the first game released in the series, which hit the PlayStation 3 on November 19 2007, and followed the story of a charismatic yet obsessive treasure hunter named Nathan Drake, who journeys across the world to uncover various historical mysteries.

Most recently, 'Uncharted: The Lost Legacy' was released in August this year, and served as a standalone expansion pack to 'Uncharted 4: A Thief's End'.

Developers at Naughty Dog had originally tried to keep the expansion short, but prior to release they found it was still amassing a whopping 10 hours of play time.

Head of communications Arne Meyer said: "Years ago, when we were asked if we were ever doing a single-player expansion for Uncharted we always said, 'Well, we don't have the self-discipline to do that.' If we tried to do that we'd create a full game.

"There's no way we could constrict and restrain ourselves, and that's exactly what was happening here. When we were doing story pitches, we were coming up with a game that would be over ten hours long and so we suddenly realised everything we said was true and we couldn't keep it short."
