Facehugger
The aim for the facehugger is to latch onto the face and implant an alien embryo. They can be found within eggs.
Chestburster
These are baby versions of the nromal adult alien and are usually be found within patients or Purvis. If you are implanted by a facehugger and have not been able to find an autodock unit, then it is game over.
Alien
