Uncharted: The Lost Legacy is the last original game they came out with, before the TLOU Remaster, and TLOU2. Legacy was released in 2017, mind you. There is also news that the fully multiplayer game in TLOU world they have been teasing for almost 4 years now, may be canceled.
They are reportedly working on a new IP at the moment, but I find this to be absolutely tiresome at this point.
It's really sad if it is the case the multiplayer game was cancelled. The original's multiplayer was absolutely great. Incredibly tense and challenging.
