Puncture (Mechanic)

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

Uses
Puncture allows bullets to pass through terrain. It is believed that upgrading puncture mods would allow penetration through thicker terrain. 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 the heads of covering enemies.

Puncture Mods can also be used in place of Armor Piercing to headshot Corpus Crewmen. This does not apply piercing damage to the bullets in of itself, but will allow normal damage and any damage modifiers to apply on a successful headshot.

Recommendation
Puncture is highly unrecommended due to its high power cost. Its rarity plagues the mods with high upgrade costs and it sees little uses other than its base value of 0.1 puncture. Rather, it is more advisable to invest on elemental damage to increase damage output as mods pertaining to it generally require less power cost.
