Methane recharge station

Methane recharge stations are portable methane tanks used by Covenant Unggoy to spare additional methane for their personal gas tanks in the field.

The Unggoy 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.

The Covenant also use a larger model of the device that can refill the methane tanks of several Unggoy simultaneously.

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 methane recharge station 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.
