I'm trying to add a few new ammo types to FNV, specifically new flavors of 25mm and 40mm grenades and missiles.. I see how to add new ammo types in the GECK, but all of the types I want to add have some kind of effect - EMP, +damage, -DT, etc. I can't figure out how to set those effects, nor how to make sure the game knows that my trusty Thump-Thump can use these shiny new 40mm HE grenades. Are there tutorials somewhere that can help me? I googled and searched the GECK wiki and came up empty.
Thanks for your time
