One Giant Leap is a Zombies-related gameplay achievement/trophy in Moon, in Call of Duty: Black Ops. It requires the player to become trapped in the Receiving Area and free themselves through "resurrection".
To acquire this achievement/trophy, two of the Excavators need to be digging into both tunnels (11 and 6) thus blocking any way to and from the spawn. A player aiming for the achievement/trophy must then get 'trapped' in the spawn room, and then down themselves and bleed out. Once dead, the player must wait for the round to end, then respawn next to their teammates. Ergo, the player has been 'resurrected' and the achievement/trophy is unlocked.
- The achievement/trophy's name, "One Giant Leap" is a reference to the late Neil Armstrong's first words when he landed on the moon in 1969.
- When this achievement is earned by a player, the song "Nightmare" by Avenged Sevenfold will play for all players.
