Recently I discovered a ship titled "Dragon Ship" in the Age of Empires II: Forgotton Empires Mod Scenario editor, and realized that as a Fast-Fire Ship, there was potential for a similar vessel in Age of Empires III. Immediately I began testing different ways of adding a flamethrower on a ship - altogether a harder task than I imagined.
This now, is a gamma version, a ship that shoots flames, but does not have a flamethrower attached on top. As it turns out, the flamethrower unit is itself an individual entity; so simply I had to copy the flame-shooting projectiles and give the ship similar tactics to a Fire Junk.
Installation instructions are included, and should provide excellent help to any who need them.
