The Vault-Tec Assisted Targeting System, or "V.A.T.S.", returns with the addition of several V.A.T.S.-specific attacks. Use of certain melee weapons trigger unique animations. Added are new weapons, a weapon modification system, the ability to use the iron sights on almost all guns (excluding several larger weapons that are shot from the hip) and a better over-the-shoulder view for third-person combat. The modification system allows for modifications such as mounted telescopic sights, rate of fire modifiers and increased magazine size. Crafting also plays a role in weaponry, with the ability to craft ammunition such as hand-loaded rounds. A plant-harvesting system similar to that of The Elder Scrolls series is also in place, allowing the player to use plants to craft special meals, poisons, and medicines.
