Arkham Horror: TCG - Into the Maelstrom

The way the scenario drip-feeds you through those tide-hollowed caves and dripping tunnels before plunging you into the hidden city is masterful pacing.

The scenario cards finally made the underwater city feel genuinely vast and dangerous. My group spent a good hour just navigating the caverns, and the tension never let up.
