Alien: 6-Film Collection - Alien / Aliens / Alien 3 / Alien: Resurrection / Prometheus / Alien: Covenant (DVD, Boxed set)

Alien
Sigourney Weaver is Ripley, the iron-willed woman destined to battle the galaxy's ultimate creature. The terror begins when the crew of the spaceship Nostromo investigates a transmission from a desolate planet and makes a horrifying discovery - a life form that breeds within a human host. Now the crew must fight not only for its own survival, but for the survival of all mankind.

Aliens
Sigourney Weaver returns as Ripley, the only survivor from mankind's first encounter with the monstrous Alien. Her account of the Alien and the fate of her crew are received with scepticism - until the mysterious disappearance of colonists on LV-426 lead her to join a team of high-tech colonial marines sent in to investigate.

Alien 3
Ripley is the lone survivor when her crippled spaceship crash lands on Fiorina 161, a bleak wasteland inhabited by former inmates of the planet's maximum security prison. Ripley's fears that an Alien was aboard her craft are confirmed when the mutilated bodies of ex-cons begin to mount. Without weapons or modern technology of any kind, Ripley must lead the men into battle against her deadly foe.

Alien: Resurrection
Two hundred years and eight horrific experiments later, Ripley's back. A group of scientists have cloned her - along with the alien deep inside her-hoping to breed the ultimate weapon. But the resurrected Ripley is full of surprises for her "creators," as are the aliens. And soon, a lot more than "all hell" breaks loose!

Prometheus
Filmmaker Ridley Scott returns to the genre he helped define, creating an original science fiction epic set in the most dangerous corners of the universe. A team of explorers discover a clue to the origins of mankind on Earth, leading them on a journey to the darkest corners of the universe. There, they must fight a terrifying battle to save the future of the human race.

Alien: Covenant
Bound for a remote planet on the far side of the galaxy, the crew of the colony ship Covenant discovers what they think is an uncharted paradise, but is actually a dark, dangerous world — whose sole inhabitant is the "synthetic" David, survivor of the doomed Prometheus expedition.
