Uncharted 4's Survival Mode, as we reported in November, is a wave-based mode where players compete to survive against a number of AI-controlled enemies (much like horde mode in Gears of War), and it is out today for players to enjoy.
The update patch comes in at 3GB, and includes new weapons, character skins, a new map, and the King of the Hill game mode, so there's plenty to get stuck into. Is Survival Mode something you'll be playing, either alone or with friends?
