Great but repetitive

User Rating: 8 | Uncharted 4: A Thief's End PS4

i bought this game 10 days before it was release, here in Ecuador it was my first time playing the uncharted series i started playing with my cousin with both saying every 10 minutes awesome game awesome game but after chapter 15 or 16 the games get to repetitive always the same outcome your start resolving puzzles and after you go out shotting so we both got a little bit tired of the game i still havent finish the game im in chapter 18 and i dont feel like playing the same thing
