The Double-Decker Bus is a civilian vehicle that was captured and repurposed by the Rebel Army.
The Double-decker Bus is a regular bus from Hong Kong and used as a roadblock due to its size. As such, there is no way of going over it until it is destroyed. The Rebels modified the upper portion of the bus to allow troops to pass through and use it as an attacking point.
- The two Chinese characters on either side of the bus when spelled in Japanese (in Kanji) is the Japanese name of General Morden. They are also found elsewhere on advertisement signs in other missions.
- This vehicle, the M-3 Rocket Launch Support Van and the Tetsuyuki are apparently the only real-sized vehicles in Metal Slug.
