Gear

Gear is a feature in Tomb Raider (2013). Salvage points can be spent on skills, which improve various aspects of Lara Croft's gear. Along with skills and its associated Skill Points, Gear form the upgrade system of the game.

Salvage
Each gear upgrade requires a certain amount of Salvage be spent on it. Salvage can be found in many different ways from collecting from a box or to using a piece of gear to retrieve some E.G using the "Torch" to burn down nets to release crates.

Parts
Upgrades only become available once enough item parts have been found. Parts allow for the weapon to be enhanced in many different aspects for example the "sight" for the machine gun allows for more precise shooting. You can add these upgrades from parts onto a weapon once you have located a "Base Camp" and selecting "Upgrades".
