About Moon
Moon arrived in the Rezurrection map pack for Black Ops in 2011. It sends players to a lunar base with low gravity, airlocks and the Wave Gun, and is remembered as one of the most ambitious zombies maps of its era.

How to play Moon online
- Use a desktop browser (Chrome or Edge works best).
- Click “Play now”. The game opens in a new tab on the original project's site.
- Wait for the first load; big games can download hundreds of MB.
- Click inside the game to capture the mouse. Press Esc to release it.
⚠ Never download a launcher or .exe from a browser game page.
Tips for Moon
- Low gravity changes your jump: use it to escape tight corners.
- Never leave the base without a way back; airlocks are your safe zone.
- Keep moving between areas so rounds do not trap you in one room.
