Trans-Siberian Trek is the seventeen level in Alternate Earth.
The level starts off on a moving train to Russia, where they must navigate through a swarm of enemy troops. Eventually, the level goes into the sky, doing flying enemies, shroob saucers and the Angry Sun before slowly descending back onto the ground. After that is a boss fight with Shoe, a Metal Slug tank, to clear the level.
