Detailed walkthrough
The alien invaders have set up advanced devices to collect data on the inhabitants of Appalachia. A mysterious ally named Homer Saperstein has remotely disabled the force fields surrounding these P.R.O.B.E.s and requests that the Vault Dwellers destroy them. Meanwhile, the UFO above will beam down alien soldiers to defend their technology.

Repel wave after wave of aliens and defeat their leaders. When the P.R.O.B.E.s are destroyed, the General Zeta will teleport down with the full force of the cosmos. Defeat him to send the invaders into retreat.

The event begins at the top of the hour (XX:00), but the location for the event differs each time the event is available.

The possible locations for the event:
 * Wavy Willard's Water Park in the Toxic Valley
 * Garrahan Mining Headquarters and Garrahan Estate in the Ash Heap
 * Monongah in the Savage Divide
 * Charleston Capitol Building in the Forest
 * Dyer Chemical in the Mire
 * Sparse sundew grove in the Cranberry Bog

No matter what, once at the area, investigate P.R.O.B.E. Kappa to be contacted by Homer Saperstein, who needs the Vault Dwellers' aid to stop the aliens from using their P.R.O.B.E. devices to collect brainwaves. He also warns to be careful as the P.R.O.B.E.s can cause energy discharges, which they give off an alert for before releasing them, shown when the device turns red and makes an audio cue.

To complete the event, the Dwellers must take out at least 30 aliens/drones at each P.R.O.B.E. to lure the commander of the P.R.O.B.E. down to fight personally. Once the commander is dead, the device's shield fails, allowing it to be destroyed.

First target is P.R.O.B.E. Kappa. Once 30 aliens/drones are down, Lieutenant Kappa beams down to fight personally, easily identified as being a slightly larger version of a cryogenic alien. Kill him and then destroy the vulnerable P.R.O.B.E.

Second target is P.R.O.B.E. Omega. Before heading towards this P.R.O.B.E., Homer will warn that the UFO overhead will be launching missile strikes and to beware of them. The spots where the missiles will be fired at will be lazed by red targeting lasers from the UFO. After flashing several times with an audio cue, the missile will drop and hit the spot, but has a small blast radius for splash damage. The spots for the missile strikes will also be marked by the icon for a grenade if the Dweller is in the vicinity of the blast radius. Taking out 30 of the aliens/probes will cause two commanders to spawn: Captain Alpha and Captain Omega, who are a pair of alien drones, who are slightly larger than the normal ones, like Lieutenant Kappa. Take them out and then destroy the P.R.O.B.E.

Final target is P.R.O.B.E. Zeta. Once enough aliens and probes are killed, General Zeta himself will beam down to attack. He is a three-star legendary alien invader, so his power armor gives him slightly better resistance to weapons, and he recovers his health once it drops below 50%. Slay him and destroy the final P.R.O.B.E. to complete the event. Again, also watch out for the missile strikes from the UFO as they will be more numerous this time to protect General Zeta.

During the attack on the P.R.O.B.E.s, aliens will attack with their drones. Some aliens are able to shoot freezing and acid rounds from their alien blasters, which is clarified by their name, "Cryogenic Alien" for cryo shots, and "Toxic Alien" for acid shots. During the assault on P.R.O.B.E. Zeta, be prepared to engage several Flatwoods monsters alongside the aliens and drones.
