Incorporeal and personal force fields

[Adder007USA]

We've started running into incorporeal creatures in scenarios and missions, and I haven't seen anyone flat out ask this.

How does "incorporeal" interact with personal force fields? I'm speaking of the brown, purple, black, etc. force shield armor upgrades.

The rules for incorporeal state that they cannot pass through force effects. Force shields, while not explicitly stated to be "force effects" are usually mentioned together with other force effects (Such as the spell "wall of force") that can block spells affected by force effects.

So in the scenario that an incorporeal creature attacks a character with a force field armor upgrade, which of the following occurs?

A: Nothing. The incorporeal creature can't pass through, nor affect the force field.

B: The creature can damage the force field, but can't do direct damage to SP or HP unless the field is taken offline first

C: Same as a normal attack, the incorporeal creature damages the target, going through the temporary HP first, with any additional damage rolling over into SP and HP.

Functionally, personal force fields are just a temporary hp reserve with fast healing, so although implied with similar language, it seems strange that a simple 1 THP brown force field upgrade could make someone immune to incorporeal attacks.

In the SFS scenario you are likely referencing, it was a plot point that the incorporeal NPC could not pass through a force field. If it could attack and damage the field, it would not have remained trapped.

Welcome to the new world, where we are much less afraid of ghosts!

Right, but said forcefield was being powered by a source OTHER than the usual batteries available to the PCs. I still feel like an official clarification would be helpful.
