The Water Slide is a Utility in the Zombies map, Shangri-La. It can only be accessed from one location and will only flow downhill. Zombies can also use it. To access the slide, go through the Mud-Pit Maze and go through the leftmost exit. At that location there is a small waterfall, behind it is the slide.It transports the player to an underground room with a Geyser. The slide is not available until the power is turned on, unlike the Ice Slide in Call of the Dead. A metal wall blocks the entrance from being used until then.
- The player travels much faster than zombies.
- Spikemores can be placed on the Water Slide, and, strangely, will stay on the slide. It will still be active, and will kill (or injure) any zombies that happen to follow.
- It is required in the Shangri-La Eclipse Easter Egg. There is a pressure plate at the exit of the slide. Three players must stay on it, while the fourth must go down the slide and activate a lever.
- The Napalm Zombie can use the water slide but it will damage him.
