Although Shane died, the Thugs preserved their reign over the first section in Seattle, and even rose their operations in the second. At the tunnel, when Delsin Rowe crosses, he encountered a looter who was shocked to discover Delsin is a conduit by labelling him a "bioterrorist" before shooting him. However, unknown to the Thugs, Delsin regenerated himself quickly thanks to his powers. He took them out, then he either subdued or executed the last one surrendering and begging him for mercy.
If Delsin chooses to redeem Abigail, the pair teamed up to dismantle the operations of the Thugs by destroying the shipments of drugs at the docks.
Around Seattle, the Thugs keep many drugs, and Delsin can eliminate the groups and destroy the drugs for good karma. They are also seen fighting police officers.
