Uncharted: The Lost Legacy features a well-scripted storyline that will take players considerable time to complete, revealed Naughty Dog.

According to head of communications Arne Mayer, the development team lacks “the self-discipline” to restrict itself when it comes to creating quality content. This mindset has been an integral part of the developer throughout the years whenever it has begun throwing ideas about a single-player expansion for an Uncharted installment. Such is the urge to not keep expansions short that Naughty Dog believes it could probably end up creating a full game instead.

“There’s no way we could constrict and restrain ourselves, and that’s exactly what was happening here,” he told IBTimes UK in a recent interview. “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.”

While Mayer refrained from mentioning how long the single-player campaign will last, it is being assumed to be over at least ten hours. Either way, fans of the franchise would be happy to know that Naughty Dog has not taken it easy for the upcoming single-player expansion pack.

Uncharted: The Lost Legacy stars both Chloe Frazer and Nadine Ross, and acts as a sequel to the recently released installment. The story is set in India, where Chloe seeks the Tusk of Ganesha. Obviously, there are other parties after the same item as well, and is where the treasure hunt gets dangerous.

Uncharted: The Lost Legacy is a standalone expansion pack, meaning that players won’t require to own Uncharted 4. This is not the first time that the developer has opted to do so. It did the same with The Last of Us, releasing its standalone expansion pack called Left Behind. However, that only ran for around three hours.
