BEFORE YOU JUMP IN

A few things
to know.

Game links and current browser details, all in one place.

About this site
Can I play BO1 Zombies in a browser?

Yes. The homepage links to the fan browser project at vel.gg/bo1z. Pick a map and let its initial data load finish.

Does this website run the game inside the page?

Play opens the linked game in a separate window or tab so this guide stays open. You choose the map on the first screen.

Which maps are available?

The current host menu lists Kino der Toten, Five, Der Riese, Nacht der Untoten, Verrückt, Shi No Numa, Ascension, Call of the Dead, Shangri-La and Moon.

Is there multiplayer or split-screen?

Current coverage describes this vel.gg browser project as solo, without multiplayer or split-screen. Native Black Ops and other browser remakes have different features.

Why does the first load take time?

The game transfers and prepares data in your browser. Keep the map open while its progress changes; no separate launcher is installed by this website.

What is Hell mode?

The host describes Hell mode as starting on round 100 with up to 300 zombies at once and no perk machines. Leave it off to learn the normal opening.

Is BO1 Browser an official Call of Duty website?

No. BO1 Browser is an independent play and guide site, not affiliated with Activision or Treyarch. Game names and artwork belong to their owners.
