So i've been playing alot of Cod WaW custom zombies recently, and i've also been trying to get into mapping. I know some of the basics, but i have a few questions:

-Is there any way I/a program that can edit pre-existing maps for my own personal use? (eg. Nacht, Der Riese, Custom Maps) I wouldn't release these to the public or anything, but I feel like it would help me learn stuff like zombie spawns, perks and debris.

-How do I make a weaponfile usable in game. I have a weaponfile ready, but every time i try to get it while in game, it doesn't show up. There aren't any good tutorials on implementing custom weapons out there, maybe one of you can help with this? (I can send you the weapon file via skype if need be)

That's all I need to know for now.  If any of you can answer these questions that would be greatly appreciated, thanks

-No, impossible
-Does Launcher give any errors regarding weapon file?

test some stuff yourself, check out some videos on YT and after 3 days you can easily build a basic map..

I learned from Rollons video, which he recently updated with some annotations on youtube
