Arkham Horror (Third Edition): Under Dark Waves

Investigators travel beyond Arkham to storm-lashed New England coastal towns where fog, missing villagers, and strange lights hint at underwater horrors. Players explore two new double-sided location tiles representing Kingsport and Innsmouth, move investigators, gather clues, and resolve encounters from a large new card pool. The game adds eight new investigators with unique abilities, new assets, monsters, conditions, and a terror mechanic that alters play. Four new interconnected scenarios present narrative objectives and escalating threats as players manage resources, combat enemies, and attempt to prevent or survive cosmic horrors emerging from beneath the waves.

Rules questions

Answered from the rulebook by Ludoya's rules assistant.

Can I pay $1 to travel between any two spaces?

No. While moving voluntarily, you may spend $1 from a travel-route space to move to another travel-route space of the same type, then continue your movement. Travel routes also have their own encounter deck (p. 4).

When an effect says “in Innsmouth,” does that include the streets and mystery there?

Yes. A town name includes neighborhoods with that name, plus streets and mystery spaces connected to those neighborhoods (p. 4).

How do I resolve a mystery encounter?

First resolve the top effect and choose one of its options; then resolve only the matching secondary effect. Don’t read the secondary effects before choosing (p. 5).

If my neighborhood has terror cards, do I still get my regular encounter?

Before your normal encounter, resolve one terror encounter using a randomly chosen attached terror card; afterward, you may resolve your space’s encounter as normal. Each investigator can resolve at most one terror encounter per round (p. 6).

Can I use an “Encounter” ability and then draw my location encounter too?

No. An encounter ability replaces your normal encounter for that round. You also can’t use one if another effect prevents an encounter, or if you’re unable to resolve one, such as while engaged with a monster (p. 8).

Can I damage a Relentless monster from another space, or keep it exhausted?

No. A Relentless monster can’t be exhausted or damaged by an investigator in another space. If you evade it but haven’t left its space after your additional action, it engages you again (p. 7).
