Reservoir Trap

The resovoir is a utility seen in Shangri-La. After opening the door next to the mud maze, the player will see a large rock. If going to the flat end, it will say "Do NOT Press X". If the player presses X (or square), a rush of water will push all zombies in the water off of the ledge, making it usefull against Napalm Zombies and Shrieker Zombies.
