Punch Through

 is an attribute that can be added to primary and secondary firearms with the use of their respective mods. Having the attribute installed allows ranged weapon damage to pass through terrain, Shield Lancer shields, corpses, enemies, and teammates.


 * Note that in Damage 2.0, "Puncture" is now known as "Punch Through"

Uses
Puncture allows ranged weapon damage to pass through terrain, Shield Lancer shields, corpses, enemies, and teammates. A basic non-upgraded puncture mod gives a value of 0.1 puncture which is sufficient to pass through the shields of Grineer Shield Lancers. A skilled marksman would be able to estimate the location of enemies' weak spots and land a shot in those spots of covering enemies. A large enough Puncture distance will allow a weapon to damage Hyena through its electric shield and is useful for hitting crouching Grineer and Corpus through railings.

Puncture distance only counts the total depth of solid material, ignoring any empty space it passes through. For example, for a listed Puncture distance of 0.6 m, a weapon's damage would be able to pass through two 0.3m thick barriers or three 0.2m thick barriers in its path to the target. However, this effect is currently very inconsistent. There are also some objects and terrain that cannot be punctured at all.

Glaive's puncture mechanic, however, does not work reliably due to its bouncing mechanic. While it will puncture though enemies and allies, it will bounce off any surfaces (e.g. Shield Lancer's shield), objects or terrain.

Tips
There are specific weapons and builds that benefit from Puncture. It sees more use on Defense type missions where thickly clustered enemies may block each other after death especially when slowed or subjected to crowd control effects. Puncture will also allow Saryn and her teammates to burst Venom Spores through unaffected portions of an enemy's body or burst multiple spores simultaneously. Finally, a sufficiently high ranked Metal Auger or Shred on Dethcube will allow the Sentinel to kill enemies who are trapped behind certain obstacles in Defense maps.
