Soon after, Gediman also discovers the creatures have escaped.

Gediman is snatched away by one of the aliens. Now loose, the aliens quickly begin to take over the ship.

When aliens begin to break through the door, Ripley escapes from her cell by punching through the door access interface and using her acidic blood to short circuit the electrical components.

The ship goes into emergency mode and some people escape in life pods; the unfortunate ones are killed by aliens, including Perez when an alien impales him in the back of his head.

The crew of the Betty bands together, but Elgyn is killed by the creatures. Ripley joins Call and the others as they make their way across the Auriga to the bay where the Betty is docked. Ripley also discovers that the Auriga is actually moving. Wren scoffs, saying she couldn't possibly know because the ship is equipped with stealth run.

However, Ripley's heightened senses are correct, the ship is moving, traveling rapidly back to homebase: Earth. The crew of the Betty is disheartened since Earth has become a polluted wasteland. They take Wren with them, although he is more of a hostage.

Along the way they find the laboratory where Gediman and the others created the Ripley clones.

Inside are the previous seven attempts, all of them hideously deformed and bizarre human/alien hybrids.

Six are dead and contained in stasis tubes.

But the seventh attempt is the most heartbreaking; she is human enough to be identifiable, yet her limbs and her body are misshapen and alien.

Even worse, she is still living, kept alive by tubes and ventilators. Ripley 8 is horrified, realizing now exactly what she is and where she came from.

Ripley 7 begs her to kill her, and Ripley 8 uses grenades and a flamethrower to destroy the other clones.

Wren is morbidly amused by her inner turmoil over her bizarre identity, and Ripley 8 looks at him in utter rage and disgust. Johner has no idea what caused Ripley's rampage; "Must be a chick thing!" he quips.

The crew makes another strange discovery: the room containing what's left of the hijacked crew that the Betty crew delivered to General Perez.

One of the crew members, Purvis (Leland Orser), is still alive, but Ripley suggests they leave him behind.

She can sense that he is gestating an alien embryo, having been impregnated by a facehugger. Call insists that they bring him along, that perhaps if they make it to the Betty in time, they can put him in cryostasis long enough for some sort of surgery to be performed on him.

A hitch in their escape plan occurs when they find that they are forced to traverse the mess hall.

Unfortunately, it is completely underwater now due to a flood that occurred during the chaos of the alien escape.

Everyone must hold their breath for a painful amount of time. Hillard dreads the thought of sumbmerging into the water.

Within moments, they are being tailed by two creatures, who appear to be excellent swimmers.

Johner fires at the first creature. When it dodges the blast, it finds a target with the creature following it, killing the xenomorph.

Hillard is snatched along the way by aliens that emerge, swimming after her. Ripley watches, strangely fascinated by the creatures.

When they emerge on the other side of the tunnel, they find that they've been ambushed; the shaft leading upwards from the mess hall has been festooned with alien eggs, which eject facehuggers at the humans. Ripley gets one on her face, but her inhuman strength allows her to easily rip it away from herself (a strange twist on the similar incident that happened to her in Aliens).

A grenade clears the shaft of eggs and allows the crew to climb the ladder to the top, but aliens emerge from the water below them and attack.

Christie (Gary Dourdan) is killed, and on the ladder, Johner is startled by a spider and blasts it point black.
