@parasurv I want to see what happens after Alien Covenant

But this tv series kinda makes sense after the avents of Alien Resurection, they are headng to earth.

However the Xenomorphs on Earth for the first time, not strictly true,

Alien vs Predator 1 and 2 both have Xenomorphs on Earth as both movies are set on Earth.

I think in the first predator movie there is a AlienHead in the Predators Lair ( i need to find and watch the first predator movie again and have a look)

However as the article says the films are not part of the Alien Franchise.
