Breach and Clear

Event: Breach and Clear is an event

Quick walkthrough

 * 1) Fight off some hostiles, usually mole miners.
 * 2) After the final hostile has been defeated, the breach is announced and a device similar to the Motherlode emerges. Boxes on this Motherlode will have lights that are initially red.
 * 3) During the event, some of the boxes will open at certain intervals (indicated by the red lights turning green or yelllow). Boxes may contain ore or junk.
 * 4) Boxes with a green light can be opened without any prerequisites.
 * 5) Boxes with a yellow light require the Hornwright senior executive ID to open
 * 6) Other hostiles will spawn during the event, including mole miners and mole rats.
 * 7) After the last set of boxes unlock a final call for box unloading is made.
 * 8) Soon after the final call, the Motherlode vanishes into the earth and the quest completes.

Detailed walkthrough
When the quest begins, all Vault Dwellers will be notified of the location where the Motherlode mining robot will be surfacing to drop off its latest haul of mineral scrap. Clear out the initial enemies in the area, usually mole miners, and the Motherlode will soon surface after warning player characters to stand clear of where it will emerge.

Once it surfaces, many of the containers on it will be marked by red lights. As the quest continues, several will change color at certain intervals. Ones marked by green lights are available immediately, but ones marked by yellow lights will be inaccessible unless a player character has the Hornwright senior executive ID to grant clearance to those containers. However, at those intervals, mole miners and other enemies will need to be eliminated before the Motherlode can unlock its next set of containers.

Once the Motherlode has unlocked its final set of containers, it will request that player characters collect all remaining loot from its containers before it submerges again. Once it submerges to begin collecting minerals again, the quest is completed.

Reward

 * Ancient blade
 * Chance to find meteoritic sword

Bugs

 * Occasionally, the containers will not contain any loot.
