I edited _zm_perks.gsc script but game uses the default script.
for example I put a "IprintLnBold("drink")" in the function where script give the player a perk bottle, but it doesn't show .
all others edits in this file don't show in game as the previous example.
How i can edit a script provided with mod tool and so it runs?

We aren't allowed to edit the default game scripts yet.

  thanks for the reply
I hope treyarch will change that...
