Punch Through is a mechanic that allows weapons to shoot through a set distance of material, whether this material is cover, objects or enemies. The total amount of material that a weapon's bullet, beam or projectile can pass through before despawning is determined by the Punch Through value (measured in meters). Punch Through is typically gained through Mods, though certain weapons have innate Punch Through values.

A basic unranked Punch Through mod gives a value of at least 0.1 meters of Punch Through, which is sufficient to bypass a Shield Lancer's riot shield. With higher Punch Through values, a skilled player can estimate and strike the location of enemies' weak spots while they're in total cover, without waiting for them to expose themselves to the player's line of sight.

High values of Punch Through can also be used to penetrate multiple enemies at once, which can greatly boost a weapon's ammo efficiency against swarms of enemies.


Punch Through is the total distance of material (object or enemy) that a weapon's projectile, bullet or beam can pass through before dissipating. This Punch Through value is gradually diminished as the projectile passes through objects or enemies. Once a projectile's Punch Through distance is used up, the projectile despawns normally as if it were fired from a weapon with no Punch Through. A Punch Through value of 1.2m is sufficient to pass through most enemies at least once (Infested Boilers being one of the notable exceptions).

For example, when using a weapon with 1.2m of Punch Through distance against a line of 4 Grineer Butchers at chest height, a shot will only pass through the first two targets but not through the third, since the torso hitbox of three butchers combined adds up to over 1.2m of material. This results in only three of the four Butchers being hit. Increasing the punch through to 2.1m will result in all four Butchers being hit[1].

It is important to note that there are some objects that cannot be Punched Through by any means; barriers from abilities such as SnowGlobe130xDark Snow Globe (both the FrostIcon272 Frost and Arctic Eximus variants) or Nullifier Crewman fields will block all projectiles regardless of the amount of Punch Through they may otherwise be capable of. Additionally, some Bosses have weakspots that periodically close, and cannot be penetrated by any means until they open up (such as General Sargas Ruk's exhaust vents, which only open after he performs certain attacks).

A demonstration of Punch Through interacting with a projectile weapon (in this case, an Acrid2 Acrid with Mod TT 20pxSeeker equipped). Note how the Acrid's darts are veering off to the right of the reticle, as opposed to continuing forward.

Beginning in Update 9.7, Punch Through now functions somewhat properly with non-hitscan weapons. However, projectiles that manage to penetrate a surface will veer off to the side once they exit, and with significantly reduced velocity.

Although Thrown Melee weapons can equip the Mod TT 20pxPower Throw mod to get Punch Through, it will only apply to enemies; the melee weapon will still continue to bounce off any obstacles it encounters while in flight.


Some weapons come with an innate amount of Punch Through without any installed mods. Most weapons with a charged shot mechanic will add Punch Through upon full charge, while their uncharged shots may not penetrate anything. In both cases, their innate Punch Through values will stack with any mods that grant Punch Through.

Average data, result will differ due to width variances.



  • A number of bosses actually become invulnerable when they deploy protection rather than using a physical barrier to block attacks. In those cases Punch Through will not allow damage to be dealt during these phases. The Raptors, Captain Vor and Lephantis are good examples.
  • SarynIcon272 Saryn and her teammates can burst Spores through unaffected portions of an enemy's body or burst multiple Spores simultaneously.


  • The Drakgoon's real Punch Through on Charged Shots may differ from the listed Punch Through in the Arsenal/Codex and on site. It seems to be even less than 1.5m as listed in the Arsenal/Codex. Further testing/info required.

Punch Through ModsEdit


  • These two containers are 22m apart, the Latron Prime has maxed Metal Auger.
  • The bullet can puncture the first, travel ~20m and still hit the second.
  • This shows Punch Through only counts solid objects, not empty space.
