Je viens de trouver une solution 
Commencer par ajouter la commande -DEVMODE comme c'est expliqué sur jv.c .
Ensuite faites une copie du fichier DevMode.lua, dans un dossier pour que vous puissiez pouvoir le ré-utiliser si vous ratez la manip qui suit.
Ce fichier doit se trouver ici (si vous êtes sur vista)
C:\Program Files\Ubisoft\Crytek\Far Cry
Pour finir ouvrez le fichier DevMode.lua avec le blocnote qui se trouve dans le dossier C:\Program Files\Ubisoft\Crytek\Far Cry .
Une fois cela fait, vous n'avez plus qu'à supprimer tout ce qu'il y a dedans et le remplacer par un copier coller de ça :

cl_drunken_cam = 0
ThirdPersonView = 0

Enregistrez les modifications, et puis... jouez 
Et là MAGIE ! si vous appuyez pendant la partie sur la toucher back space ( donc celle qui sert à supprimer et qui se trouve au dessus de la touche entrée ... ) vous basculez en god mode, et donc vous êtes immortel 
Alors, merci qui les noobs ?
