This seems like an underbar to me, really.  Why not just say that advanced warriors often have extra weapons built-in?  We can include a typical stat block if you like, but I'd honestly just include the variant Integral Weapons text.
		
		
	 
I think including the stats would be more useful, although I'd be fine putting them into a compressed format such as the "Dungeon magazine compact block" type, e.g.:

*Many Warrior Droids substitute another Int-based skill for their     crystal card's Search skill, such as Craft, Disable Device or Knowledge.
 Integral Weapons (Ex): Warrior droid can use weapons and wear   armor like a standard character, but most also have built-in weapon   systems. Integral weapons are powered by the droid's internal energy   plant, so they will not run out of power as long as the warrior droid   continues functioning.
A heavy warrior droid has a high-frequency sword built into one arm, a  concussion rifle in its other arm and a laser pistol in its head.  Targeting sensors give  the heavy warrior droid a +3 racial bonus to its  rifle and laser's attack rolls. The  droid does not provoke attacks of  opportunity when it attacks with its  integrated laser, despite it being  a ranged weapon.
