Running and jumping requires stamina. So before you dive deep into buildings, make
sure you have food and water. Once you are low on stamina, you might find yourself stuck at the bottom of a building! IF you are low on water/food when entering a building, find some friendlies or cabinets, they are slightly skewed to give you a higher chance of water (I don’t want you to die).
Sleeping restores your health. You’ll have your home assigned to you pretty early, so use the bed there or use random beds in buildings after you killed all monsters nearby)
New skills #
Experience unlocks skills. All your actions give experience, and with experience you can unlock new skills. Very important for your survival. Skills can be unlocked at a skill-table, you’ll always have on at your home but they are also available in random buildings.
Got lost? The compound is often the start for most missions, or if it’s not there are often friendlies around that you can talk to and they will point you to nearby missions.
Safe space #
Avoid contact early in the game or when low on food and ammo. You can find a lot of stuff at the compound, which is a safe area of buildings, and then slowly make your reach bigger from there.
