All of these questions could be answered in the form of a mod that bridges the gap between DX and DX:IW.
You play as Helios as you escape the collapsing Area 51 and have a set time limit or whatever. There seems no need for extensive weapon modding but it would be a nice bonus.
Just here to plant a thought into someone's head.
NOTE: I take no credit if the mod is created, just acknowledgement. Remember I didn't do anything and we'll all be cushty
