Naughty Dog have announced at the 2016 Sony Playstation Experience conference that they will be releasing a standalone DLC to Uncharted 4 which is called Uncharted: The Lost legacy. The game takes place after the events that took place in Uncharted 4 with the main characters being Nadine and Chloe with the location being confirmed as India.
They have mentioned that they will be expanding the concept of wide linear gameplay and will feature more open areas than that in Uncharted 4. Chloe is apparently the best driver in the business so the game will feature more driving elements, which I am glad to hear as I personally loved the 4×4 outback driving segments in Uncharted 4. Chloe’s fighting style and move set will also be different from what player’s are used to when controlling Nathan Drake.
