Lol long time since i posted here, yes there is a way, its in my logs somewhere but i really dont want to dig in it heres the deal. goto the level with the church where u get cleansed, then use changelevel to get to the seconds level where you wake up in bed, then give yourself the weapons from the console, SAVE GAME AND BACKUP when done so u can use it in the future
You could also just use GCFScape to change models.
