Unfortunately WaW is considering the cg_fov dvar as a cheat Although you can launch the map using "devmap mapname" to play with cheats. Although some maps like dead sand elite will abort themselves when cheats are on.

Oh, thanks a lot man, it works will at least the ones I'm playing!

I suspect this have been discussed numerous times, but please forgive my ignorance, since it's day one for me.
I would like to ask you is there any way to change my FOV to 75 for example. I can't do that in any custom map, I have keys binded for that, but still they don't work unless for the original maps. I suppose there's a mod tools restriction for custom maps for reading FOV from config file or console, otherwise anyone would make their maps with a customizable FOV, or Am I wrong?
I saw Comosea have a separate FOV bar, which probably just confirms that the custom maps are not able to use cg_fov other than 65. Is that the case and if it is, can I do anything about it?
Thanks in advance!

Hello, fellas! Great project! I'm playing COD since the first one in 2003, but only recently I started custom zombies.
Amazing project, keep up the great work.
