We'll call it the gaytomizer
I could see possibly adding an instant hit particle beam weapon(with the normal colored power levels), dubbed the 'Gatomizer' - since it could be able to shoot & destroy(atomize) weapon projectiles(unless shielded against it somehow), since it would be cool to deny homing weapons that lock on!
But, all that would also depend on your aim & power reserves too!
I'm also leaning toward favoring an almost silent but deadly, very fast rail gun - and to make it cooler, you could even use amber tracer rounds with it!
A tentative name for it could be the 'Regulator'☺
Anyone have any ideas for a focused Sonic or Microwave weapon? That would send any well equipped bot with very sensitive audio detection circuits screaming in retaliation!
