Methane recharge station



Battlefield Methane Tanks are equipment used primarily by Covenant Grunts.

The Grunt's homeworld, Balaho, is a methane-rich planet and as such they breathe methane gas. Thus, when they are in a oxygen-rich atmosphere, like that of the Halo installations or Earth, they need to wear a methane gas tank. When Grunts are in battle, they may run low on their supply of methane, so they must have a ready supply nearby if required. These tanks contain the ready supply of Methane Gas the Unggoy need.

They are short and round in shape, purple in color and have a large blue valve on the top. The Methane Tanks are seen generally where Grunts are operating. The tanks are also highly explosive due to their methane content.

Trivia

 * If the blue "X" on the tank is shot at it will ignite and burn for a while before exploding.
 * Battlefield Methane Tanks appear only in Halo 2. In gameplay terms, they are similar in function to Plasma batteries in Halo 3, as both explode when shot at.
 * They seem to resemble Gravity Thrones that the High Prophet Hierarchs use.
 * A new version of the Battlefield Methane Tank appears in Halo Reach. It is highly explosive and will start to leak gas when it is about to explode. They can hold four grunts.
