Ok, Here is a way you can use a Missile with Smoking mirror's Chemical Attack "Gas". This is just a copy of the Cruise Missile with changed Name, INI, Sounds and Recommended Editor Settings for use.
Be SURE and get Smoking mirror's Chemical Attack and add it to this Chemical Missile Unit.
Just Change the Name of the ChemicalAttack.flc to ChemicalMissileDeath.flc and add it to the folder.
Unzip (Extract) the following Zips into a new Unit Folder you name Chemical Missile ...and use the space in the name.
Other than making some sounds and putting this together with the INI and Recommended Editor Settings that work well for using this Missile, these Zips are just to simplify what anyone could do. That said...try it out, I think it is a real "Hoot".
get Both #1 and #2 Zips.
