“Alien Invasion” is the opening song for the third ZOMBIES movie, released on July 15, 2022. The song was released two weeks before the film’s release, the song served as a trailer for the film and a single for the soundtrack.

With electronic music elements, the song marks the arrival of the aliens in Seabrook City on Earth, a true alien invasion! The city is on alert even the aliens say they came in peace, because the ships end up causing a lot of damage in the city, for example explosions in cars and light poles. With the arrival, humans and zombies get scared, werewolves are on alert because they think aliens have come to steal the moonstone. Afterwards, everyone gets together to fight the aliens, which ends up not working out very well because of the aliens' force fields. In the middle of the invasion, a person got carried away with the aliens, which is Addison (Meg Donnelly), the only one who was in the middle of the chaos that was happening in the city, but Zed (Milo Manheim) runs after Addison and the two start a conversation in the middle of everything and that then is closed because the floor was opening up. In the same place that the ground opened up, the aliens go and find an ancient spaceship, talking about having completed its mission and found Utopia, a perfect world for the alien community to live and thrive, just needing to find what is most precious in Seabrook City.
