A ww2 mod for Half Life stole your sounds. I won't go into details, but various sounds for weapons, and Germans speaking, were stolen. You can download the mod here:
War In Europe mod site
Now, I personally would think this is a big deal, but I don't know if it is to you guys. I would sue them, if it was my property, and stolen. Or, they could have already asked you to use the sounds. If they did, I apologize.
Note: You have to have Half=Life to play the mod, and verify that what I'm telling you is right. However, I'm not lying, but I know you'll want to verify this for yourself. The map I played was a omaha beach type map, and the sounds might only be on it, so make sure you test out that appropriate map.
The mod sucked so bad, I didn't play any others.
Figured you might want to know about this.
