Albeit it still works, however there are (for unexplainable reasons) problems with the Napalm Strike firing from the Command Center. Therefore I use the Propaganda Centre for mine (Use whatever you feel is right.)
Anyways onto the Tutorial
Firstly open FactionBuilding.ini and locate:
Object ChinaCommandCenter Behavior = OCLSpecialPower ModuleTag_16 SpecialPowerTemplate = SuperweaponNapalmStrike OCL = SUPERWEAPON_NapalmStrike End
Cut/Copy the Module Tag and find the Propaganda Center (Or Whatever Building you choose).
Object ChinaPropagandaCenter Behavior = OCLSpecialPower ModuleTag_30 SpecialPowerTemplate = SuperweaponNapalmStrike OCL = SUPERWEAPON_NapalmStrike End
Feel free to add it whereever on the Building you use and I suggest using a higher number rather than 16, as 16 is taken on most buildings. Anyways, in terms of buildings, your done! Onto the CommandSets!
Locate the building that is using the superweapon and add this line
CommandSet ChinaPropagandaCenterCommandSet XX = Command_NapalmStrike CommandSet ChinaPropagandaCenterCommandSetUpgrade XX = Command_NapalmStrike
XX of course being the number that you use & of course it's on the upgrade command set otherwise when you upgrade to mines you'll lose the command
I suggest (and this goes for all buildings) putting the Superweapon off to the right. This way it seperates units/technology/superweapons
With that your done. Load up the Game and test out your Napalm Strike
