If you are experiencing problems finishing the Wasteland Classic mission, make sure that all upgrades for ‘The Jack’ Archangel are GREEN, except for the Baby Bars armor upgrade. In order to access the Archangel menu, press ‘X’ on Xbox One, ‘Square’ on PS4, or ‘F’ on PC (default key map) in the Garage menu.
Important Note: In order to finish ‘The Jack’, you may have to install lower level parts than the ones you currently have installed. This includes getting rid of some upgrades entirely. These upgrades need to have a GREEN circle on top of the upgrade in the Garage menu.
