Jim and Leo go on a simple jaunt through the asylum... (Arkham Gauntlet 2 | 13 | ARKHAM HORROR) 

I think this and Circle Undone are worst for scaling for solo. In this campaign you have multiple strong enemies and often have only one action as you are using the others to discard treacheries. In Circle Undone you have the Spectral Watcher draining your actions to evade/defeat it. By contrast, much of Scarlet Keys is easier in solo, because the concealed mechanic is simpler to manage if the enemies come one at a time, and depending on your actions you can go into the final scenario with an absurd number of allies/keys under the possession of a single investigator.

I haven’t played the Scarlet Keys - but i am planning on getting it next so that’s good to know. Yeah enemies like the Spectral Watcher and the Hunting Horror are exponentially more difficult in solo as you have noone to pull focus.

@@jamesstanley4691 I hope you enjoy playing Scarlet Keys when you get it - it has a lot of replayability because of all the routes you can take with the scenarios and interludes, as well your choices of who to ally with and who to deceive.
