The Slug Trolley was designed to walk over rails. It's a custom mine cart equipped with a Vulcan. Pressing down opens its hatch, allowing the player character to toss grenades.
Like the Donkey Slug, it can attach additional wagons to itself (up to four, two on each side), which are equipped with unlimited cannons. The wagons will be lost if they are hit. Getting through the stage with any number of attached wagons will score you a bonus 100,000 points for each wagon.
In Other Games
The Slug Trolley appears as a playable unit in the 1.32.0 update.
Its Special Attack is deploying a wagon from above to attach with the Slug Trolley (up to 4 wagons can attach). Its wagons work as extra power for its standard attack; the more wagons attached, the stronger its attack Once the Slug Trolley attaches all of its 4 wagons, its special is changed to a cannon barrage. Each wagon will shoot all at once, for a total of four shots. Unlike in Metal Slug 7/XX, the Slug Trolley's wagons are invulnerable.
- This was previously called the Slug Truck before it got renamed in Metal Slug XX.
