Help making Cascade Missle OXP

[ArkanoiD]

New barely usefull weapon: the Pelter Cannon.

Fires miniature 'missiles' at the target each pellet does relatively little damage if it happend to hit home, but each round triggers the ECM of said ship to fire (or to fill the PLAYER screen with 'INCOMING MISSILE' messages)
This distracts the quarry AND drains the energybanks.
pellets selfdestruct at 5000m travelled.
Drawbacks:
-Ship needs huge bank of missiles, so NPC only.
-Missiles still need to be locked individually: requires auto-targetter/arming software to be effective.

Sngle missile exploding with multiple warheads may help to use that on player ships..
