Black Ops developer Treyarch is bringing the battle royale genre to Call of Duty: Black Ops 4 later this year with Blackout, a franchise-first mode that will introduce the largest multiplayer map Call of Duty players have seen to date.

A new trailer for Blackout released today by Activision and Treyarch shows off what Black Ops 4 players can expect when the game hits PlayStation 4, Windows PC and Xbox One in October. Players will fight on familiar destinations like Nuketown, Hydro and Cargo, all connected by a massive map that will support dozens of players. As seen in the new trailer, players will be able to fight in air, on sea and on land — and against zombies.
