The doors to the Communications Tower in Hadley's Hope A:CM

These doors to the Comm Tower of Hadley's Hope can be found at the end of the Underground Tunnels

Winter and O'Neal get here during the mission No Hope in Hadley's

Past these doors you will find a legendary weapon, Gorman's Pistol


This door is initially locked and will stay locked until you and O'Neal kill all the Xenos in the area.

It might look like you are stuck but just use your Motion Tracker to locate and kill all enemies in the area and then the door will open.
