i am not trying to crash your hopes and dreams ... I am just saying you might want to do some more research into the engine. I don't think it can be recreated( those weapons) but i could be wrong.
continue developing your mod, your doing a good job. (Don't let the moderator get to you! he is up to something evil! :P)
bare in mind aswell guys that changes are happening all the time... reading various modding topics on various forums has definately taught me that the ability to do something in the engine is as easy as flicking a switch on and off... ok, maybe not THAT easy but if we all pester EA and DICE about it we should get plenty more functionality :D
