Most of the data for all the SR3 weapons is still there, some of them even still have their models. Now, implenting weapons costumes and such is LEAGUES away. We haven't even figured out if we can add weapons back in or not. Lets concentrate on the here and now, then once we find out if we can do silly things like make it so weapons costumes can be added to other weapons, then we'll go about making it so there are Stag costumes for the Alien guns. After that, we can just implement them like most of the game.
