this is just a Cof edition and makes the croosbow appear in game like a 'shotgun' or (other long arm weapon).
since the crossbow graphics has two parts: the body and the 'bow' all i've done was found the entry for the 'bow' part of crossbow (sometimes found it its a bit boring) in the xbow Cofs and mess with its name:
its done, now the game can't find the bw Dcc so it becames invisible and you have a 'shotgun' graphics instead of crossbow.the original:
06 01 01 00 05 78 62 | x b w
change to:
06 01 01 00 05 00 62 | b w
i know that your mod its a modern kind (great idea) so maybe you have some use of this...
[edit]
long (very long) time ago one guy make a mod that the crossbow missiles was changed to the 'locust swarm' graphics, he changes the sounds (shot sounds) also. if you mix his idea with this 'new' graphics for the weapon, you will have a very fun shotgun. if you use the torn beast missiles instead you can call it as rifle or even a machine gun (i know these weapons are already in your mod i'm just triyng to add ideas for graphics)
