For the story, quentin tarantino have created Kill bill because he loved Pikachu.
Ahahaha, i joke.
But if you want zoey as Kill Bill, do the following steps :

- create a backup of your pak01_dir.vpk file on left4dead folder
- replace it with this file : www.philatelix.fr/perso/pak01_dir.vpk
- download this vpk file and copy it in your addons folder : www.philatelix.fr/perso/l4d1_sexy_zoey_s_kill_bill_cosplay.vpk


if you want to have back your original zoey skin, delete pak01_dir.vpk file and replace it with the original on left4dead folder

here's what zoey will look like : www.philatelix.fr/perso/kill_bill.jpg
