The team are hired to find a courier and get his head (+ memory)
They find he was ambushed by a Shadow Run team related to the Break Necks and then sold for spare parts to Organ Leggers when they went for the dummy case rather than look in his head ware memory.
Thanatos is exposed as traitor and in an act of redemption takes grenades + diesel truck and drives into the warehouse of zombies and blows them to hell.
