I dont know if this is right place but, i have now tried to get all barcodes for mården bunker for 8h. I have killed about 35 bots nearby mården, but i only have gotten one barcode. Help me.
In general the barcodes are dropped by runners.
They are just dropped by FNIX machines, which shouldn’t be the problem in that region. The bunkers in marshlands and north coast region can be more difficult regarding this.
Sometimes it helps to fast travel to another region and to come back later. Or to play in another world or as guest in multiplayer.
At least, after 4h the machines and loot should be renewed.
I can’t say more than that’s just random luck. But the game should in general help you to get them quickly.
