Weapons are components on an airship. There are two different sizes, light and heavy. Different ships can equip a fixed amount of guns at fixed (light or heavy) gun slots. As a weapon gets destroyed, it will emit a blue shine similar to other components being destroyed. A destroyed weapon will be non-functional in terms of usage and reload of the weapon until rebuilt.
Part of existing weapons available in both Skirmish and Alliance mode, another part unique for Alliance only.
Light guns are the most common weapons in Guns of Icarus Online. Light guns can only be placed in light gun slots. Light weapons generally don't hit as hard as the heavy weapons, but can still wreak a fair amount of havoc with quicker loading times and versatility. The gun health is 200 HP.
Heavy Guns
Heavy guns are currently the largest weapons in the game available on a playable ship. Heavy guns require heavy gun slots, which are not available on all ships. The gun health is 425 HP, more than light guns, but it also takes more time to rebuild gun. The heavy gun has a bigger hitbox than the light gun.
Damage Types
Each weapon has up to two damage types. The first damage type is applied for direct hits (primary damage) and the second damage type is applied for AoE hits (secondary damage) (see also Hit Mechanics). Hitting a destroyed component will transfer damage (also fire stacks) to the armor, then the hull.
Each class can equip at least one special ammunition type. They can affect every individual stat of the gun they are used on. When a gun is loaded with a special ammunition the gun symbol of the component indicator changes to the symbol of the ammunition type. Therefore it is possible to tell the loaded ammunition by just getting close to the gun.
While applied the effect of the Dynabuff Industries Kit increases the weapon damage by 10% and stacks additively with damage effects coming from ammunitions, and also reload speed is reduced.
Crosshair and Arming Time Indicator
HUD of gun show additional information around crosshair like ammunition count, loaded ammunition type, reload progression, and HP of the gun. Range Finder can give an additional golden indicators on crosshair which are designed to improve aiming, but raise doubts in terms of practical use.
Weapons with arming time additionally have an arming time indicator that shows a dot on each side of the crosshair in moment when the shot is armed.
