If you just picked up the remaster or dusted off your disc copy, learning how to black ops 1 unlock all zombie maps is the fastest way to stop replaying Kino der Toten on loop and actually see the whole Zombies story. Black Ops 1 shipped with two base maps and then expanded through four DLC packs plus a bonus remaster pack, so "unlocking everything" really means owning the right content and, in a couple of cases, finding a hidden menu trick. Here's exactly what unlocks what, in order.
The Base Zombies Maps: Kino der Toten and Five
Kino der Toten is available from the moment you boot the game — no campaign progress required. It's the intended starting point for new players and the map most guides recommend learning first.
Five (the Pentagon map with JFK, Nixon, McNamara, and Castro) is different: it's tied to campaign completion. Finish the Black Ops 1 single-player campaign and Five unlocks automatically in the Zombies menu. There's also a well-known workaround: entering "3ARC UNLOCK" on the in-game computer at the Zombies main menu unlocks Five without beating the campaign, and typing "DOA" unlocks the hidden arcade cabinet game, Dead Ops Arcade, the same way.
DLC Maps: Ascension, Call of the Dead, and Shangri-La
Three more maps came as paid downloadable content during BO1's original release cycle, and on PS4/PS5 (via backward compatibility or remaster) you'll need the corresponding DLC pack purchased and downloaded to your account:
- Ascension — released in the First Strike map pack, set in an abandoned Soviet cosmodrome. Introduces the Gersch Device and the monkey bombs.
- Call of the Dead — from the Escalation pack, the George A. Romero zombie-movie-themed map starring real actors as playable characters, plus a fifth playable character (Sarah Michelle Gellar as "The Nomad").
- Shangri-La — from the Annihilation pack, a jungle-temple map with a minecart system and one of the trickiest traps in the series (the Lava/Gong puzzle).
If your library is missing any of these DLCs, they simply won't appear in your Zombies map select screen — there's no in-game trick to unlock them; they have to be owned.
| Method | Ban risk | Speed | Works on your own account |
|---|---|---|---|
| Legit boosting service | Low | Fast (hours) | Yes |
| Manual grinding/unlocking | None | Slow (many hours) | Yes |
| Save-file glitch/edit | Moderate to high | Fast | Risky, can corrupt save |
| Mod menu / hacked save | High | Instant | Yes, but flagged easily |
Moon and the Rezurrection Pack
The final chapter, Moon, along with remastered versions of the four original World at War Zombies maps (Nacht der Untoten, Verrückt, Shi No Numa, and Der Riese), all came bundled in the Rezurrection map pack. Moon closes out the "Origins" storyline that started in Kino der Toten and requires the Gersch Device and Wave Gun to fully explore, plus a squad of four to complete its main Easter egg. Like the other DLC maps, Rezurrection has to be purchased and installed — there's no free unlock method for it.
What "Unlock All" Actually Requires
To have every Black Ops 1 Zombies map available at once, you need:
- The base game (Kino der Toten is free)
- Campaign completed, or the 3ARC UNLOCK code, for Five and Dead Ops Arcade
- First Strike DLC for Ascension
- Escalation DLC for Call of the Dead
- Annihilation DLC for Shangri-La
- Rezurrection DLC for Moon and the four classic WaW maps
Beyond just owning the maps, actually playing them well takes rank, perks, and unlocked weapons — which is where most of the real time investment goes. If you'd rather skip the campaign grind and jump straight into every map with your account properly leveled, the Black Ops 1 Unlock All & boosting service handles that setup for you.
The Fastest Legit Way to Get There
Grinding out a full campaign clear plus tracking down four separate DLC packs on PS4 or PS5 can take a long weekend even before you touch a single Zombies match. Some players look at "unlock all" mod menus or modded lobbies as a shortcut — but those run on modified save data or third-party tools that can flag your account and risk a ban, since Activision actively monitors for tampered stats and illegitimate saves. It's not worth losing access to a game you paid for over a shortcut.
The safer route is a boosting service that plays on your actual account using legitimate methods — no injected saves, no mod menus. MessyModdingStore's Black Ops 1 Prestige, Rank 55 & Unlock All service gets your account to max rank with everything unlocked without you having to grind campaign missions or hunt down DLC installs manually. It's aimed at players who already own the content and just want the unlock/rank process handled quickly and safely.
Frequently Asked Questions
Can I unlock Five without finishing the campaign?
Yes. On the Zombies main menu, use the in-game computer to type "3ARC UNLOCK" and Five will become playable immediately, no campaign completion needed. This works alongside "DOA," which unlocks Dead Ops Arcade the same way.
Do I need to buy every DLC pack separately to black ops 1 unlock all zombie maps?
Yes, on PS4/PS5 each map pack — First Strike, Escalation, Annihilation, and Rezurrection — has to be purchased and downloaded individually (or included in a bundle/remaster edition) before its maps show up in your Zombies menu. There's no cheat code that substitutes for owning the DLC.
Is using a modded lobby to unlock everything safe?
No. Modded lobbies and mod menus alter save data outside of normal gameplay, which is exactly the kind of activity anti-cheat and account monitoring systems look for, and it can result in a ban. A legitimate boosting service that plays through normal matches on your account is the safer alternative if you want the process sped up.
Once you've got the maps unlocked, the real grind is rank, weapons, and perks — if you'd rather have that handled for you safely, check out the Black Ops 1 Prestige, Rank 55 & Unlock All service from MessyModdingStore and get straight into every map fully equipped.
