This version of Hastur is a Massive punishment for 2 - 1player just for taking the doubt option. The scenario turns out a hell in that situation. The other two versions are waaaay softer compared to this. For such a good campaign as Carcosa is, I consider this card its only flaw: Nearly impossible to beat doubt mode in 1-2 players mode no matter how well you played the campaign. And you find that out at the end.
