Punch Through

Puncture is an attribute that can be added to primary and secondary firearms with the use of their respective mods.

Uses
Puncture allows ranged weapon damage to pass through terrain, Shield Lancer shields, corpses, enemies, and teammates. Upgrading puncture mods increases the distance damage is dealt beyond the point of initial impact through solid objects (does not count air). Some game objects can not be punctured however. 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 effect will allow a weapon to damage Hyena through its electric shield and is useful for hitting crouching Grineer and Corpus through railings.

Tips
Modding for puncture is usually inefficient due to the high mod capacity requirement for a relatively mediocre effect even at max rank. Its rarity plagues the mods with high upgrade costs and it sees few uses other than its base value of 0.1 puncture. Rather, it is more advisable to invest in damage mods such as Elemental or pure damage to more efficiently increase damage output, as those mods generally require lower mod capacity. The exception to the above is the Shred Nightmare mod as it offers a massive puncture distance along with a desirable fire rate bonus.

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.
