Approach him and he will ask what the Sole Survivor wants shortly afterward, he will engage the Sole Survivor in combat unless they say the deactivation code obtained from Mama Murphy. One may intervene in time to prevent the rest of the Gunners from being killed. One refuses to give it to him and will be executed. Once there, the courser can be heard threatening some Gunners for a password. On the seventh floor, there is an elevator that goes up to the top of the building.
These explosions will not affect the player. Missiles are being fired at the courser (who shrugs them off). Reaching the fifth floor, a salvo of explosions can be heard. The courser is just ahead the whole time and easily eliminates his opposition, littering his path with Gunner bodies. The player will have to fight their way up through the building. He orders the majority of his troops to retreat up the building and the rest to engage the Sole Survivor. Upon entering the building, the commander of the Gunners starts issuing orders over the intercom. Greenetech Genetics is filled with Gunners who are fighting Z2-47, the courser. Tune to it and follow the signal east to Greenetech Genetics.
The 'courser signal' will be available on the Pip-Boy's radio at that point. After receiving the quest, travel to the C.I.T.
