Alright, this is an interesting tag. It was originally found on the FS1 Disruptor missile. If you fired this weapon at a cruiser, it would shut down for a short period of time; all the turrets would lock and the engines would stop dead. It never got much attention because the missile was introduced late in the FS1 campaign, didn't last very long, and there was no FS2 counterpart. The tag was still in the code, though, as the D-Missile still works in FS2.
Can we explode this tag like we did with the Corkscrew flag? Have some table set parameters, like intensity, weapon-duration, engine-duration, and beam-duration. Intensity can be used as a multiplier with the duration parameters in the same way damage is done, and affect different ships different amounts (via HP.) A standard FS1 D-miss would shut down a Cain for 30 seconds, a Lilith for 20, and a Demon for 10, for example. Then you can have really high intensity weapons but that only affect beams; lots of stuff you can do.,
Making this avaliable as a flag for primaries would have some very interesting results. We could have SW style ion cannons, where on impact the ship is disrupted for a short period of time. Or, apply it to beam weapons. The beam can act like a tractor beam, holding the taget disarmed and immobile while it is captured, or while more powerful weapons are brought to bear.
If somebody could look into the workings of this tag, and apply these ideas, there are lots of possibilities.
EDIT: Can we have critical lightning dance across the hull as an option? For SW ion cannons, that is.
