This stage is based on the first area of Shadow Moses Island in Metal Gear Solid: a helipad located outside a tank hangar and connected to a nuclear weapons disposal facility. In the aforementioned game, the facility's searchlights are focused on the helipad itself. If Snake is caught by the light, his cover is blown and guards are called to kill him. The searchlights remain focused on him until he finds somewhere to hide. Ever since Metal Gear Solid, if the player is seen by security, the trademark exclamation point is displayed over the enemy's head, and the corresponding sound effect plays. By Metal Gear Solid 4: Guns of the Patriots, the island is sinking under the Pacific Ocean due to global warming, including the facility now left deserted a decade after the Shadow Moses Incident. Its design in Smash is slightly different than the original game: the staircases are missing, the truck that was parked in front of the building is gone, and the height of the searchlight towers have been extended. If a player gets caught by the searchlights in Smash, an exclamation point will appear over the player who got caught, and the same sound can be heard. The searchlights will also follow that player for a short time.
