I have my custom shotgun.vc ready, But i want to know is how can i have the player start off with it loaded with 50 shotgun shells just like the player stating off with the pistol. And also is there a way i can expand the attack range or reach of the chain saw in one of the progs.vc files? i'm turning the chainsaw into a lighting gun.

Check the Player class, it has a function that gives the player his initial inventory.

Yes, one of the line attack function's arguments is range.
