A few fantacy ideas:
Area Affect Weapons
Affects
1 square at range 1 with say 90 Hit Points
3 Squares at rage 2 with 30 Hit Points
5 squares at range 3 with 10 Hit Points

Bouys Launcher
If it could launch
30, 60, and 90 Hit Point Bouys
that explode on impact.
in a "line"
They could be destroyed by PDC. These might slow down the advace of a threat while you pummle it with longer range weapons.

Multi Target Weapon
It will hit any target in the line of fire with each target recieving less damage.

Hard coding for these probalby makes them unlikley.

I refuse to profer a logical how it works for any of these.
