The newest Design Journal has explicitly given us a new challenge.

Playing Undimensioned and Unseen in stand-alone mode with 4 separate ultimatums.

• Ultimatum of Invisibility – Each Brood of Yog-Sothoth (Undimensioned and Unseen, 255) gains the Elite trait and is immune to all player card effects except for the effects of Esoteric Formula (Undimensioned and Unseen, 254).
• Ultimatum of Multiplication – Instead of the standard setup instructions, begin the game with all five Brood of Yog-Sothoth cards in play: one in each of the five locations besides Dunwich Village (Undimensioned and Unseen, 242). For the remainder of the scenario, whenever an effect would cause you to spawn a set-aside Brood of Yog-Sothoth, you must instead place one doom on the current agenda.
• Ultimatum of the Keeper’s Challenge – Investigator decks cannot include any of the following cards: Elusive (Core Set, 50), Astral Travel (The Path to Carcosa, 34), Cat Burglar (Core Set, 55), Mists of R'lyeh (The Forgotten Age, 29), Lure (The Essex County Express, 156), Think on your Feet (The Dunwich Legacy, 25), Shortcut (The Dunwich Legacy, 22), Shortcut (The Pallid Mask, 232), Survival Instinct (Core Set, 81), Survival Instinct (Undimensioned and Unseen, 235), or Pathfinder (The Miskatonic Museum, 108).
• Ultimatum of Agony – When assigning damage or horror from a single source, investigators must assign as much damage or horror as possible to a single card before any excess damage or horror may be assigned to a different card.

The next scenario on my first Dunwich legacy campaign is Undimensioned and Unseen. I'll have to replay it later to try for these achievements! I wonder if this format will replace the achievements from the Return to the Night of the Zealot.

Argh, I have three solo campaigns going and I still haven't played RotNotZ yet. Now I have to make time for this?

Meh. Not a big fan of this type of stuff. I generally just play the provided material as designed. If someday I end up playing a lot more than I currently do, MIGHT decide to try it.

Fair enough. I love this kind of explicit challenge. Someone on BGG was going to run some but stopped after just one. I'm glad to see FFG putting them out.

I made my first attempt a couple of hours ago.. Managed to kill one out of five, so still a long way to go.

The benefit of challenges like this is that I don't have to rebuild the encounter deck every time I want to solo, I can just leave it ready to play and have a go whenever I feel like it. Lovin' it.

Congrats on getting one, which investigator did you use? I haven’t tried yet, but it looks so hard that even getting the Esoteric Formula seems like quite the challenge.

I used Ashcan Pete, so I was able to grab clues with Duke while moving to the location. Solo, so I just needed 2. Spent most of my rounds just evading, though.

I got one Brood with a Sefina deck, then two after I tweaked it for more clue power. I'm sure I could have done better but I had the worst possible map -- Devil's Hop Yard let me add one clue, and 10 Acre Meadow let me add one TEMPORARILY.

After two attempts, Leo Anderson finally killed all five Broods.

Wow, nice work! Care to share your deck and/or strategy?

So I'm pretty sure Jim Culver just walks down easy street for this challenge. His Chaos Bag has SIX "0" modifiers in it.

Good call. It's still not easy, but the two Skulls are essentially auto-fails (-10) at the start.

Building it now - a Pair of Protective Incantations and either Lone Wolf / Forbidden Knowlede + Sylvestre to pay for them and you can remove the 2 "-5"s.

**** he doesn't even need to investigate he can just Drawn To The Flame for his 2 clues

I chose to go with Leo Anderson because of his high Will power and Combat. His Intellict is also high, allowing me to gather clues necessary for environmental abilities, and act progression. I had Leo Deluca (Lev 1) to give me an extra action, beat cops and Brother Xavier to help with the weakness enemy and thralls as well as damage soak from the Dynamite Blast (Lev 2). I also had El-Amin in play to help with resource generation.

For the Broods, I had about 4 environments that I could utilize for adding clues to the beasts. I got lucky drawing the elder sign when evading twice, as well as for the final kill. I also was lucky on the enemy draw as they were mainly treacheries.

Rules question: you're supposed to add a doom to the current agenda when a Brood would spawn. The "#b" agendas spawn Broods. But those are also the current agenda. So no doom is added to anything, right? Or more technically, a doom is added to the "#b" agenda and then immediately removed from play when the next agenda comes up.

That's a good question. It never occurred to me that those doom tokens would also be removed, but reading in the rule book it says:

"To advance the act deck or the agenda deck, follow these steps, in order: Remove all tokens from the card to be advanced. If the agenda deck is advancing, remove all doom from each card in play"

So I think you're right that the tokens would not be added to the next agenda. Which might just give me the few extra rounds I need to complete the scenario!

Nevermind, further reading has left me unsure again. The removal of doom happens before the agenda flips to side B

Here's the complete order of things:

1. Remove doom

2. Flip Agenda to side B

3. The next card in the deck becomes the current act/agenda

4. The advancing card is simultaneously removed from the game

Since the two last steps happen simultaneously, I'm unsure what takes precedence. but I'm leaning towards the advancing agenda still being the "active agenda" while the text is being resolved (so the doom would be removed along with the card)

You're missing "read and apply the instructions on side B" between 2 and 3.

My interpretation is based largely on rulings about Miskatonic Museum, where a B-side agenda may spawn the Hunting Horror, but since the B-side agenda does not say to add Shadow-Spawn, that doesn't happen. The B agendas are active agendas just like the A sides, and going from a B to the next A removes doom that would have been added to B, which almost never happens but, it seems to me, would here.
