To mark the release of Uncharted: The Lost Legacy, Naughty Dog will be rolling out an Uncharted 4 multiplayer update that adds a new playable character, The Lost Legacy character skins, and a new co-op challenge mode called "Survival Arena."
This update, which is set to rollout the same time as The Lost Legacy’s release on August 22, will introduce new skins for Chloe and Nadine pulled directly from The Lost Legacy, and the standalone expansion’s antagonist, Asav, will also be playable in multiplayer and Survival Arena.
Survival Arena is a "new take" on co-op Survival mode that adds over 100 new waves with new enemy types, new Siege zones, and all-new wave modifiers. Fortunately, this update will be available for both Uncharted 4 and The Lost Legacy, and the community for both games will be unified, so you can compete and team up with your friends regardless which game you or your friends own.
Lastly, Uncharted: The Lost Legacy stickers for Apple devices will arrive on the App Store. Check ’em out below.
