6. Alien
How To Survive: Do the exact opposite of everyone else around you. Ellen Ripley is the protagonist and total badass of the Alien series; she's a smart, resourceful character who survives through so many films because she actually sought to question authority and defy the orders put before her. She wasn't afraid to stray from those around her, as well as the Weyland-Yutani company, who are represented by both androids and slimy lawyers throughout the series. While the rest of her team are picked off by making stupid decisions (like getting themselves cornered), Ripley stands alone as the only person who seems to have a honed survival instinct. As a result, if you ever find yourself being hunted by a Xenomorph, simply look at what those around you do, and do the opposite.
