What Is Alien: Earth About?
Alien: Earth is set decades before the events of the original Alien film and takes the franchise to an entirely new setting — our own planet. The story unfolds in a near-future where powerful corporations, including the infamous Weyland-Yutani, are pushing the boundaries of science and ethics by experimenting with human/synthetic hybrids.
