The Gas Mask is a Head armor that can only be obtained by purchasing the said bundles. This item has a special ability of increasing the damage of the Incinerator by 25%.
- Both this and the Close Quarters Mask have very similar appearance since they both function as "Gas Mask".
- It's the only armor piece in the game that lists the specific weapon that it can boost.
- Thus, it's the only head armor in the game to only boosts one weapon.
