Weapons that can fire on full, or semi-auto will cause additional hits (to a Horde).
And then it never says how many additional hits.
For example Semi-auto… how do I determine the additional hits?
And don't you dare say "one for every two degrees of sucess" I'll have to hurt you. That is standard behavior for semi-auto fire… I'm asking how to determine my 'additional' hits.
It tells (and is errata-ed) how to assign additional hits for blast weapons, and flame weapons, and explosive damage weapons…
But not the simplest case of semi and full auto-fire.
