This mod requires the Loader and Template Extension to run.
Note that this mod is only Mercy's outfit.
Her hair can be found here: Mercy Static Hair (Alternate hair can be found here, this one is a .png file)
A combination .swf (which has both the hair and costume in 1 file) can be found here: MEGA
The above Google Drive link is to a .zip file, which contains a folder you can drop into your Mods folder of the Loader and instantly have a call to Mercy at your whim (as long as you add the appropriate line to your CharacterFolders.txt file). The .zip folder also includes standalone versions of the hair and costume. I've elected to host the combination mod off-site as I see no need to post what would basically be the same mod twice (the costume and hair are unique, the combo mod is literally just both together).
