Creating ProtoUnits (custom units) via the .quest file

This is a slightly different tutorial, as everything you need to know is written in the .quest file as a <!--Comment-->.

The .quest file and a .age4scn file are contained in the zip archive. Simply dropping them into your "Age of Empires Online" root directly will do the job. Allow it to overwrite any folder, but it should not overwrite any files.

To read the guide, open the .quest file in your favorite text editor (I suggest Notepad++)

When loading the quest in the offline editor, it will pull the map, quest objectives, and custom unit. It will also spawn a map with the "Queen Boudicca" (Custom Headhunter) in the center as an enemy, with varying groups of units on the outskirts to test her with (Persian and Babylonian primarily)

To edit the Line of Sight of a unit, add <LOS>#</LOS> between <overrides></overrides> and <ProtoAction></ProtoAction>
