Prisoners of War

Prisoners of War is a side quest in the Fallout: New Vegas add-on, Honest Hearts.

This optional quest is received simultaneously with Flight from Zion along with Retake the Bridge and Sanctity of the Dead.

Detailed walkthrough
The Courier should make their way up to Ranger Substation Osprey. Encounter four White Legs guarding the prisoners. If the player character is of high enough level, one or more of the guards may be armed with brush guns.

After defeating the White Legs guards, the player character needs to open the cell to free the three prisoners. To do this either lockpick the Hard locked cell door or find the key in a toolbox upstairs in the Ranger substation tower. Either solution gives the same amount of quest XP, excluding the bonus XP for successfully picking the lock.
