Ammunition. This cartridge appears to be armor-piercing ammo for the HN Needler Pistol. The hypodermic tips are made of a strong alloy and are incredibly sharp.

HN AP Needler cartridge is a ammunition type in Fallout 2.


Despite being an "armor-piercing" ammunition, this HN breed doesn't actually change a target's normal DR. It does have the 2/1 modifier, though, and so will deal a lot more damage.

When loaded with the AP ammunition, the Needler pistol will actually deal more damage than the Gauss pistol against lightly armored targets.
