The Villeneuve Mt. System is a chain of mountains where the rebel plane Tetsuyuki crash-landed. This area features many huge seafaring vessels marooned in places they could not realistically travel to, such as a large regular army submarine of unknown origin stranded in the middle of a dried and relatively shallow riverbed, and what appears to be an oil tanker trapped in a lagoon beneath a waterfall where the Tetsuyuki is located.
- This area is presumably located in Southeast Asia, due to its jungle environment and a large Siamese/Cambodian idol encountered at the beginning of the level.
- This is further evidenced in Metal Slug Defense; when selecting the Southeast Asia level, the backdrop shows the Villeneuve Mt. System.
