Methane recharge station



Battlefield methane tanks are used by Covenant Unggoy to spare additional methane for their personal gas tanks.

The Unggoy's homeworld, Balaho, is a methane-rich planet, and as such, they breathe methane gas. Thus, when they are in an oxygen-rich atmosphere, like that of the Halo installations or Earth, they need to wear a methane gas tank. When Unggoy 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 Unggoy operate. The tanks are also highly explosive due to their methane content.

Trivia

 * If the blue "X" pattern on the tank is shot at it will ignite and burn for a while before exploding.
 * A different version of the battlefield methane tank appears in Halo: Reach. It is highly explosive and leaks gas when it is about to explode. It is capable of simultaneously refilling the methane tanks of four Unggoy.
