Ok, I am including three different versions of this. It appeard that the creators of the Birth of the Federation Mod didn't know that Armada II will crash with the AI or Automony using Self Targetting Regenerative Weapons and possibly all Self Targetting Weapons. I am totally disappointed with this so I have attempted to create a New Hull Polarization weapon for the NX-Era starships.

This Mod Package has three different version of the Hull Polarization Weapon (you can say there are 6 if you count the futuristic version for the 25th Century NX-class Refit)

1) The Original that crashes the game for your reference if you want to attempt using it. It works when you select it but if the AI or its selected automatically, the game will crash. (Use those files at your own risk).

2) This version is based off of a special weapon entitled "Beam Reflective Shielding". It is set to bounce/reflect Beam Weapons and also Torpedos in my self-created Hull Polarization version. This version of the Hull Polarization weapon uses the Corbomite Refractor's texture. 

NOTE: When I tested this ingame, my Fleet of 16 Yorktown-class Battlecruisers was decimated by 4 Romulan Enterprise Era Bird-of-Prey Motherships. It is like the Yorktown-class Battlecruisers didn't have any weapons at all because they barely used them. All 4 Romulan ships remained, usually two Yorktown-class starshps could take out the Motherships, 16 should have destroyed all of them as "Overkill". (Thus the conclusion is- This version of the Hull Polarization Special Weapon might need more testing and tweaking to make it work correctly.)

3) This version is based off of a special weapon entitled "Damage Control and Secondary Shielding". The original version (as in the Damage Control and Secondary Shielding weapon description was: "Increases shield recharge rate through secondary generators and initiates automated repair systems.") and for my self-created Hull Polarization version using this file, I just renamed the file and changed the Toolips and Weapon Name to reflect the Hull Polarization weapon. This version of the Hull Polarization weapon uses no texture at all. It does though still have the Regeration weapon category. It has no coding telling it what to target. 

NOTE: I haven't tested this version of the Hull Polarization weapon in my game, but I have had the "Damage Control and Secondary Shielding" weapon in my game for almost 2 years without any problems, but to be honest, I have never really thought if it was really active or not even after using/activating it. So I really don't even know if this Special Weapon is working or if this one will, I know the game has never crashed with it though and the "Damage Control and Secondary Shielding" is actually being used on many ships the AI can play against me and is also being used on the ships of other races, all without crashing. (Thus the conclusion is- This version of the Hull Polarization Special Weapon might still really needs to be tested and might need some major or minor tweaking to make it work correctly.)
