Salvage

"We're gonna need Salvage, A LOT more"

- 'Samanya talking to Alec Mason to help her with the Nano Forge''

Usage
Salvage is a key item in Red Faction: Guerrilla. Salvage can be used to buy Red Faction-made weapons and and upgrade the weapons by either enhancing their abilities, adding more abilities to the weapon or even just having more ammunition for that weapon. You can also buy equipment like Armor or story-mandatory equipment. You use Salvage at upgrade tables which can be easily identified at Safehouses with Samanya working at the Upgrade Table. Note that it won't be in the garage building with the weapons locker and a vehicle of the Safehouse but at the small hut near it. Salvage is the currency in Red Faction: Guerrilla and is used by Samanya to purchase certain equipment on the black market (never seen in-game just talked about once or twice throughout the whole game).
