I have one question:
In the next release of nexuiz the new weapons will spawn alternately with old weapons with the same weapon's areas(crylink/assaultrifle camprifle/machinegun seeker/hagar)?Or will have new separate weapon's areas for the new weapons?

I believe it's at the server admin's discretion. Right now I'm using cvars to replace weapons with one I consider close to equal.
