Ok, so first of all amazing mod it really improves the gameplay without changing the feeling of WaW zombies.
 
Next, I noticed that the demonic announcer is always in english. My game is in spanish and the characters voices use the spanish translation except on natch (because there was no translation) but for some reason the demonic announcer voice is in english.
 
Is there a way to replace the english audio file for the spanish one or make the map use the spanish audio?
