I am a bit rusty on the rules but brushing up on things because I am going to be GMing a game again. Scatter guns are the slugthrower version of a shotgun and I cannot find any specifics on scatter guns and deflect. So I was curious, is there a set of errata rules I am unaware of and more importantly, do any of you have house rules for them that you recommend?

I had a player bring this up when they found the weapon. Their character is from a more primitive world and they were thinking it may be able to partially bypass deflect, which does make a degree of sense. I am half debating on treating it like an AoE weapon that only impacts one square.
