Methane Wagon

The Methane Wagon is a modified version of the Shadow.

Overview
The Methane Wagon is an unstable, slow, and rickety modified version of the Shadow created by Unggoy. It has a parking brake made of a chunk of wood. The Methane will detonate violently when its structural integrity is compromised due to the volatile infusion-enriched methane stored on it.

Armament and support
The vehicle emits a Methane aura, clouds of infusion-enriched methane, that makes nearby Unggoy aggressive. The wagon can also catapult kegs of Methane that release enriched gas clouds of the infusion-enriched methane.

Operational history
In 2559, when Yapyap rebelled against the Banished during their battle with the crew of the on Installation 00, Yapyap had a few Methane Wagons under his control, hoping to upgrade them.
