Deep Impact

The Deep Impact perk is used to shoot through higher density materials such as brick, metal sheating, concrete blocks (not solid concrete walls), all for reduced damge. It also causes more damage when shooting through lighter materials like wooden fences and drywall. However, it DOESN'T cause anymore damage to an exposed enemy than it normally would.

If this perk is used together with stopping power, the damage from stopping power will effect the damage done when shooting through heavy material. However there are some materials that just can never be shot through... so dont get the idea that Deep Impact allows you to shoot through everything.
