Ripley transmits a panicked SOS from the Nostromo, the trailer begins. She's in deep trouble, facing imminent threat, declaring herself the sole survivor. A voice, supposedly Romulan, declares this isn't Ripley at all. This shapeshifting extraterrestrial has commandeered the vessel, and vows to inflict harm on Ripley.
The preview hints at a battle over the ship's governance, the alien apparently seizing control of critical functions. The creature expresses a wish to escort Ripley back "home." The concluding statement references the alien's voracity, implying a danger to both Ripley and the craft.
The trailer employs humor and replicates Alien tropes extensively. The terrified Ripley, coupled with the parody of a "game over" situation clearly point to the comedic approach. The preview most likely mocks the Alien saga with over-the-top language and scenarios.
