I had an idea for a good AVP 3 movie and I'll show a long brief version of my plot on this board. If you like it I will post a detailed one but it could get very long.
Note: there are no characters yet.
February 4, 2122 (a few months before the events of Alien)
Due to a scout ship losing contact and disappearing unknown space, a small military cruiser near the scout ships last known location holding colonial marines and other personnel goes searching for the scout ship. Near the origin of SOS call, the ship discovers a small planet and lands there. They then set out search parties for possible survivors. Later, one search party discovers the crashed scout ship. The marines are confused for there are no bodies.
Meanwhile, a Predator ship lands after locating life signs matching human and xenomorph identity. The cloaked ship lands and 2 Predators depart from it.
The search parties regroup, but 1 squad of engineers find an odd, large cave. They enter but then hear the regroup orders. They hesitate when they discover human bodies and a dozen eggs. They begin to hatch and the marines open fire, all marines are facehugged except for one, but a grown alien cuts off the exit. After the disappearance of the squad all marines set out another search for them.
It gets dark and the personnel onboard the ship who stayed behind are all killed by aliens who enter through the main door, carelessly open and guarded by marines. Soon, the search parties are chased back by aliens to the ship.
Later, 2 Predators enter the jungle and are involved in a brutal battle with aliens using gadgets and hand to hand combat.
Meanwhile, the remaining soldiers contact Earth, only to reach Weyland Yutani Corporation. The marines tell them that "something" attacked them and that there on a planet, which was enough for the corporation to get there extremely fast hoping to finally get an there hands on an alien
The aliens find a way in the ship and the marines are forced into battle, the survivors run into the jungle where there predators attacked them 2 marines stayed behind and the predators got trophies. The remaining humans met up with the Weyland corp. and after telling them about the aliens, they attempt to kill them for they are witnesses. The humans flee into a nearby cave. Several minutes later, Weyalnd corp. attempts to catch an alien but are soon wiped out by aliens and a predator, while the other predator follows the marines.
In the cave, the humans run into a queen alien and 2 Praetorian guards. One predator gets into a fight with the queen, while the other predator fights the praetorians. The humans find a Weyland corp. ship and enter it. The humans leave the planet. The predator fighting the Praetorians dies. It tells the other predator "run" and activates its self-destruct device. The other runs to his ship and leaves the planet. The explosion kills all the aliens. The predator on its ship is then surprised when it sees the queen on his ship. They then battle and the predator sticks an explosive on her and ejects her, she explodes in space. The predator, mortally wounded dies in his ship.
Meanwhile, Mrs. Yutani asks about the aliens, her secretary says that it's unknown what happened on that unknown planet. She asks if there is any ships close by and he says yes, a ship called the "Nostromo". She says good, we still have a chance.
