Life paths

Nomad starts in the Badlands, Street Kid in Heywood and Corpo in City Center. They only change dialogue and some early options, so choose the story you like.

Attributes and perks

Attributes range from 3 to 20, and perk tiers unlock at 4, 9, 15 and 20. Attribute points can be reset once, and perks can be refunded freely, so experiment. Phantom Liberty adds a sixth attribute, Relic, with a nine-ability skill tree.

Skills

Skills level up passively as you use them, with a bonus every five levels up to 60. Levels 15 and 35 give one extra perk point each. The five trees are Headhunter, Netrunner, Shinobi, Solo and Engineer.

Weapons and playstyles

There are Power, Tech and Smart weapons, with colour-coded rarity. Damage types are Physical, Thermal, Electric and Toxic. Ripperdocs install cyberware, and the two classic playstyles are Netrunner (hacking) and Solo (combat). Street cred, earned from side quests, unlocks vendors, gear and quests.
