Stages of Evolution

• Stage 1 Egg
• An egg that is laid by the Alien queen.

Stage 2 Facehugger

• Egg releases a facehugger that crawls around on
  its legs and tries to attach itself to a hosts
  face where it can then deposit the embryo into a
  digestive track. The facehugger soon dies
  afterwards

Stage 3 Chestburster

• Once the embryo fully matures in the hosts
  digestive track, it burrows its way out of the
  hosts chests, killing the host in the process.

6
Stage 4 Alien

• Overtime the chestburster fully matures into a
  full grown alien. The period of time is unknown
  and varies from movie to movie. In Aliens vs.
  Predator it was believed that it was roughly 1
  minute from egg to this stage of evolution. Bad
  movie that makes no sense? Maybe.

Stage 5 (Optional) Alien Queen

• Not every xenomorph progresses to this stage but
  the alien queen is the final stage of evolution
  which allows for the release of more eggs for the
  cycle to begin anew.

Methods of Killing

• Pretty common sense stuff to killing the alien
  basically. In the Alien movies, most
  conventional weapons worked however xenomorphs
  have high agility to landing a direct hit is
  rather difficult. Its best to approach them in
  squads.
• In Aliens Ripley was able to defeat the Queen
  xenomorph with a giant construction robot.

Closing

• I know its from Predator but the line that
  Arnold Schwarzenegger used in the original
  Predator movie applies to the Xenomorph
• You are one ugly mother fer.
• But theyre still interesting enough to have lots
  of information on them though
