ABI's economy runs on Koen, earned by looting cash and valuables, selling on the marketplace, and completing missions. Spend it on gear, ammo, meds, insurance and — in high-tier zones — extraction fees.
Traders / Contacts
Each trader specialises: weapons, armour and backpacks, meds, and so on. Completing their missions builds reputation, which lowers their commission and unlocks better stock. Prioritise the traders that sell what your build actually needs.
Factions & missions
Factions such as MNST and CDIS hand out weekly missions that grant reputation and faction currency; that reputation unlocks further factions and rewards. Work Main, Faction and Weekly missions together — they are the backbone of progression and the fastest route to a stash that pays for itself.
