Climber. Climbing is a natural movement mode for a Facehugger. The creature gains a CLIMB speed equal to its regular SPEED and does not need to make checks to climb. The creatures can move on walls and ceilings normally.
Pounce. The Facehugger can jump up to 12’ horizonatally, or 6’ vertically, to attack its victim. On a successful attack, it attaches itself to the victim’s face; the victim gains the Restrained condition at severe level (requiring a 6 to remove). Each round that the victim begins its turn grabbed, he takes 3d6+3 damage, which cannot be SOAKED. When reduced to zero HEALTH, the victim falls unconscious, but does not form a death countdown - the Facehugger keeps its prey alive and impregnates it. Any damage to the Facehugger at this time does damage to the victim, also, making it very hard to dislodge (although an extended Strenuous  LOG (medicine) task with one-hour intervals will do it). The Facehugger leaves the victim after 24 hours. The victim, now impregnated, forms a 3d6 hourly countdown pool. At two dice, the victim feels uncomfortable and slightly feverish; at one die, the victim feels considerable abdominal pain; and at zero dice, a hatchling xenomorph bursts from the victim’s body, killing him instantly.
