Wasteland 2: Director's Cut (EP)

Ranger Team Delta is the Rangers' "internal audit team", tasked to go after rogue Rangers. For this trophy you need to go on an NPC killing spree in 2 separate locations. Once you have committed the 2nd atrocity, a radio message will be sent to you informing you of Delta coming after you. This situation isn't desirable for the Platinum and the story so reload afterwards. Save first. The first time you do this, someone radios Ranger Citadel about you but Vargas gives you a pass but the 2nd time you do this, Vargas doesn't give you a pass and once this happens the trophy will pop. Keep killing until the radio call happens.
