That'd be this · http://www.moddb.com/mods/swwm-full-pack · and only 2 guns of it's nearly 30 could do it.
Not practical unless you're hosting those weapons, of those specific guns. Can't expect everyone to have those, especially as they're a major memory drain.
So I've been trying to find something else that can too.
There's a disintigration spell in the Dark Magik mutator I didn't get a chance to try yet, lot of competition for spells when you've got 16 bots running around. That might be able to do it.
