Noisy Cricket

I would like to see a high lethality low mass high point cost weapon for
smaller ships. Such a weapon should have the following limits:
  Limited to forward arc and being the only weapon.
  Other than point defence weapons, it is the only weapon that can be
fired
in turn of fireing.

Range 0 to 24 mu fires one dice hits 3, 4, 5, 6..
  3 = one point damage
  4 = one point damage
  5 = three points damage pentation like K-gun
  6 = nine points damage  pentation like p-torp

 mass 2, ten points per mass,  for a total of 20 points.

Shield shift die roll -1 point per level.

A great weapon for small ships but a waste for big ships.
