Cinematic Knockback

In reality, guns cause little or no
knockback. But in cinematic combat,
a big gun can blast foes through win-
dows and even walls! Work out
knockback for a piercing attack just
as if it were a crushing attack. In
addition to rolling to see if he falls
down, anyone who suffers knockback
from any attack must make an IQ roll
or be mentally stunned on his next
turn. This roll is at -1 per yard of
knockback.
