Penetration kills in MW3 are needed to get certain daily challenges completed. You can then unlock additional killstreaks by completing these tasks.
What do you need for Penetration kills in MW3?
In order to gain penetration kills in MW3, you’ll need armor-piercing ammunition for your gun. You can unlock this type of ammo by completing two daily challenges. But first, you need to assign the goal reward in the Armory Unlock menu. Press triangle (or Y on Xbox) on the Party screen.
Next, find the armor piercing ammo. It’s marked by an emblem that has three grey fallen ammo pieces underneath three that are standed. Make sure this reward is selected and then it says Active on the top right of the box.
Once you’ve completed two daily challenges, the attachment will be available to you. Attach it to an assault rifle or LMG that’s level 9 or above.
How to get a Penetration kill
In order to get a penetration kill, your bullets need to pass through a wall before hitting your foe. The cover can’t be too hard because the bullet won’t go through it. Try to find a wall that’s made of wood to get the penetration kill and attack your foe as they approach. Get a proficient headset on and listen out for nearby soldiers running towards a point in Domination if you’re behind wooden cover.
While the Drexsom Prime-90 optic can’t see through wood, I found it excellent to spot enemies with its thermal view on the area.
