Nathan's brother, Sam, offers Nathan their last adventure, on their way to find Henry Avery's hidden treasure in order to save Sam's life.
Uncharted 4: A Thief's End is the last game in the series, and honestly, it's the perfect ending for Nathan's story.
The story is surprisingly good; the plot seems simple at first, but the writing, the dialogue and the characters are awesome, and they make up for the simplicity of the plot.
The gameplay is quite simple as well, but it's enjoyable and it feels satisfying.
The graphics and the audio are absolutely incredible! Uncharted 4: A Thief's End is probably one of the best looking games I've ever played and it has some spectacular set-pieces.
Now... although the ending itself is awesome, I felt like the last few hours before the ending were a tiny bit tedious; in fact, the pacing in general feels slightly padded at times.
Also, while the combat system is fun, the gameplay loop feels monotonous and basic for the most part.

Pros:
+ Great narrative
+ Likable and engaging characters
+ Dialogue/humor
+ Fun gameplay
+ Superb visuals and set-pieces

Cons:
- Inconsistent pacing
- Repetitive gameplay loop

Narrative: 8/10
Gameplay: 7/10
Characters: 9/10
Music: ?/10
Graphics/Audio: 10/10

Final Rating: 9/10
- Amazing -
Uncharted 4: A Thief's End is better than the sum of its parts and it's another fantastic experience from Naughty Dog, and a masterful sequel for the entire series.

Do I recommend it?:
Highly recommended for PS4 owners and must-play for Uncharted fans.
