I am back from Emerald City ComiCon with Jason C. Hill's answers to our questions.
Can Heroes with three hands triple wield guns or dual wield a one- and a two-handed weapon?
Yes and yes. This is still considered "dual-wielding" so that there can be no Critical Hits .
If an Enemy is adjacent to a Hero and does not change targets, should it move to be in back of the Hero or stay where it is?
As currently played, they stay where they are.
When Lava Men move adjacent to a Hero, should they move as far as possible or choose a Lava space to enable healing?
As currently played, they stay where they are.
Authority of O'Tar: "Attacks +1 Damage in Otherworld." Is this treated as if it said "Hits +1 Damage in Otherworld”? Or is +1 Damage added to the attack as a whole?
Add +1 Damage to each hit in the attack.
Jason included the "as currently played" disclaimer because these rulings could change when the official FAQ (in the works) is released. He also took pains to remind us that we are not forced to play by these rules. "If you want to make the Lava Men more challenging, have them move to lava spaces."
He also said that he looks in on this page a couple of times a week. If we were to compile a large list of questions for him, it is likely that they would be answered (when he has time).
The first couple of mission packs may - *may* - be available at GenCon. No promises! It's likely that they will receive wide release in the fall. Likely, not certain!
Also, he has pretty much convinced me to pick up Forbidden Fortress just for the Belly of the Beast Otherworld.
