In Call of Duty: Black Ops 6, round-based Zombies means surviving successive waves of undead while exploring a map, completing objectives, and spending resources to open routes and strengthen your weapons. The August 2024 reveal announced two launch maps: Terminus and Liberty Falls. The game launched on October 25, 2024.

How round-based Zombies works

Zombies arrive in rounds, putting survival at the center of each match. Players must decide when to fight or evade, where to explore, and which purchases or upgrades will help them handle the next wave. Treyarch’s official Terminus overview describes matches as a mix of fighting waves of undead, exploring, and completing objectives. A match supports up to four players: you and as many as three additional teammates.

The map’s routes and systems make resource decisions part of that loop. Killing zombies earns Essence, which can be spent to open routes, buy perks, upgrade weapons, refill ammunition, and access other map systems. Salvage drops from enemies and supports weapon rarity upgrades, Ammo Mods, and crafting tactical, lethal, and support equipment. These are distinct resources with different uses, so what you spend can shape how you prepare for later rounds.

Which Zombies maps were revealed for launch?

Activision announced two new round-based maps for launch. The reveal contrasted Terminus’s remote prison-island setting with Liberty Falls, a small West Virginia town caught in a zombie outbreak.

#1 Best Overall
Call of Duty®: Black Ops 6 - PlayStation 5
  • Developed by Treyarch and Raven, Call of Duty: Black Ops 6 is a spy action thriller set in the early 90s, a period of transition and upheaval in global politics, characterized by the end of the Cold War and the rise of the United States as a single superpower.
  • This is signature Black Ops across a cinematic single-player Campaign, a best-in-class Multiplayer experience, and the epic return of Round-Based Zombies.
  • The Black Ops 6 Campaign provides dynamic moment-to-moment gameplay that includes a variety of play spaces with blockbuster set pieces and action-packed moments, high-stakes heists, and cloak-and-dagger spy activity. 
  • In a best-in-class Multiplayer experience, players will test their skills across 16 new maps at launch, including 12 core 6v6 maps and 4 Strike maps that can be played 2v2 or 6v6. 
  • Black Ops 6 also marks the epic return of Round-Based Zombies, the fan-favorite mode where players will take down hordes of the undead in two brand-new maps at launch. Post-launch, players can look forward to even more exciting maps and groundbreaking experiences dropping into both Multiplayer and Zombies.
Map Setting and scale Map-specific weapon
Terminus A prison complex in the Philippine Sea, described by Treyarch as one of the largest round-based maps, with prison, ocean, and smaller-island areas to explore. Beamsmasher
Liberty Falls A more compact small town in West Virginia experiencing a dimensional breach. Thrustodyne Model 23

The map descriptions and weapon details come from the official Terminus overview and the Liberty Falls gameplay showcase. They distinguish the maps by setting and exploration, not by a supported easy-to-hard ranking.

Terminus: a prison island to explore

Treyarch presented Terminus as a large island prison environment with routes to open, objectives to complete, and a main quest. Its remote location and surrounding ocean give the map a different sense of place from the town setting of Liberty Falls.

What customization and weapons did the reveal highlight?

The Liberty Falls showcase described several ways to prepare and adapt. Augments can be researched between matches and applied to Perks, Ammo Mods, and Field Upgrades. GobbleGums are selected in a pre-match pack and obtained from machines during play; the reveal specified four GobbleGum machines in Liberty Falls.

The Ray Gun was presented as a returning Wonder Weapon. Liberty Falls also has the map-specific Thrustodyne Model 23, while Terminus features the Beamsmasher. The official showcase described the Thrustodyne’s rotor speed as more than 40,000 RPM; that is a game-design detail, not a real-world performance benchmark. These are reveal-era descriptions, not a complete account of later balance changes.
