In addition to his gun, Darkwing is able to use three special weapons, after finding them within the levels. You can switch from your basic weapon to the special weapon obtained by pressing . However, you can only use one special weapon at a time: if you take a special weapon when you already have one in your possession, the first will be replaced. Each time you use a special weapon, you will consume a certain amount of gas. The gas you have is shown at the top left of the screen, under the type of special weapon you have. To restore your gas supplies, you will need to find the relevant canisters. Each time you get a new special weapon, your gas supply will be increased by ten.
HEAVY GAS When fired, a large ball of gas will fall to the ground and explode. The explosion will send a shock-wave across the floor in both directions. Heavy Gas uses 2 units of gas energy.
THUNDER GAS Darkwing fires two lightning bolts that moves at 45° angles up and down. Each bolt will pass through enemies and walls until it flies off screen. Very useful for hitting enemies without being in their line of fire. Thunder Gas uses 2 units of gas energy.
ARROW GAS When fired, the gas takes on the form of an arrow with a suction cup moving in a straight line. If the arrow hits a wall, it will stick to it, allowing Darkwing to climb and stand upon it. Thanks to this weapon, you can then reach otherwise inaccessible areas. Arrow gas deals high damage being the most powerful yet the most simple weapon. It is also the rarest special weapon to find. Arrow Gas uses 3 units of gas energy.
