One of the new weapons on our TODO list is the Electrolaser, which is basically a ranged version of the stun rod, operating as per the standard electrolaser principle:
http://en.wikipedia.org/wiki/ElectrolaserThe model for this weapon has been completed, and can be found in SVN base/models/weapons/electrolaser
What we need now is a particle and sound for the firing effect. Once we have that we can implement it right away. hoehrer will post a mockup image later on.
If there's anything you can do, don't hesitate to post!
