The script adds two missions with aliens from GTA Online.
In the first mission, at the request of Omega, you must visit Fort Zancudo, sneak into one of the military hangars and collect spaceship parts there. In the hangar you will see a real flying saucer with aliens, and the hangar itself will be guarded by professional fighters from MerryWeather.
This mission almost completely repeats the new business battle from GTA Online, added with the Los Santos Summer Special update.
In the second mission, an alien ship crashed into a swamp near Fort Zancudo. Omega will ask you to examine the wreckage and collect parts from the crashed ship. This time, instead of the military, aliens will appear on your way. They will appear near you at random times and use a stun gun. And although it practically does not cause damage to the player (only if you are not in the water at that moment), alien attacks will in every possible way prevent you from collecting all the parts of the spaceship.
The plot of the mission has been changed, and the gameplay itself has become more complex and interesting.
Both missions are only available for Franklin!
Missions are launched randomly. In one session of the game, you can only complete one of the two missions. If the task fails, you need to restart the game in order to receive a message from Omega. The mission with the crashed spaceship is only available at night. The mission to steal ship parts from the hangar is available at any time.
