And it sounds exactly like a horde mode. With 50 waves of increasingly more powerful enemies to take out, upgrades and defenses to build, treasure to collect, and a special boss encounter every 10 waves. Called Uncharted 4: Survival this new co-op mode is expected to drop mid-December and comes hot on the heels of a recent PlayStation 4 Pro update to the game -- which makes what's arguably 2016 prettiest game, even prettier.

Check it out.

If you played Co-Op Arena from Uncharted 2 and Uncharted 3, you’re going to feel right at home in Survival. We’ve built upon and evolved the core gameplay experience with an entirely new level of depth, challenge, and variety. From new enemy types and powerful new bosses to a dedicated progression system and expansive upgradable arsenal, Survival is all about strategy, camaraderie, and skill.

Across 50 waves and 10 maps, you’ll face off against Shoreline mercenaries, heavily armoured Brutes, Snipers, Hunters and more, that will only get more precise, more aggressive and better equipped as time goes on. Every 10 waves culminate in an intense boss battle, including our all-new Pirate Warlords.
