Safehouse

Safehouses play a main role throughout Red Faction: Guerrilla. At Safehouses you can buy Upgrades with the Salvage you have found and spend it at the Upgrade Table where you can buy new weapons/equipment at. Safehouses are also where you can hide from the EDF if your Alert level is at red because once you get to the safehouse the alert level will be green again. You can also switch out your weapons and get ammo for them too at the Weapon Lockers. Safehouses are also where you will finish Transporter missions, Collateral Damge Missions, and House Arrest missions. They also usually have a vehicle with a weapon attached to it in the Garage. You will also respawn here if you ever die in-game

Trivia
It is possible to provoke the EDF to attack a safehouse, if you attack a convoy or an APC and then return to base. Your alert level will not return to normal, and the EDF will keep coming (albeit usually in small groups) until the convoy or APC is destroyed or reaches it's destination. It's a good opportunity to see the Red Faction use those turrets they have lying around safehouses.
