When the Revolution Comes is a zombie-related gameplay achievement/trophy featured in Buried for Call of Duty: Black Ops II. This achievement/trophy requires the player to make it back to the starting room.
To return to processing, players have to destory two fountains. The first fountain is located in front of the church, where players have to use Arthur to smash and destroy it. The second fountain is located within the maze, and it can be destoryed using explosives weapons such as grenades, the Ray Gun or the Ray Gun Mark II. Destroying both fountains fill the second fountain (within the maze) with liquid, effectively turning it into a portal to the spawn.
Note that a player do not destory the first fountain before entering the pit of the maze fountain, he will be killed when trying to enter it.
- The name of the trophy/achievement is a reference to the phrase "first against the wall when the revolution comes" from The Hitchhiker's Guide to the Galaxy. The other part of the phrase is also an achievement: FSIRT Against the Wall.
