Shuffle the encounter discard pile into the encounter deck.

(→R1)

Each investigator with 5 or more cards in his or her discard pile takes 1 horror. Each investigator with 10 or more cards in his or her discard pile takes 2 horror, instead.

If the players have completed The House Always Wins, advance directly to agenda 2b. If Extracurricular Activity is the first scenario in the campaign, advance to agenda 2a.

Shuffle the encounter discard pile into the encounter deck. Then, discard cards from the top until a location is discarded. The lead investigator resolves that location's 'revelation' effect.

Check Campaign Log. If at least one name is recorded under "Sacrificed to Yog-Sothoth," read the following:

"You hear a familiar voice calling out to you, and you enter an impossibly shaped building of cracked stone. "No… don't!" the voice cries. You rush toward the voice, down a set of steep, narrow stairs. Upon reaching the bottom, you find yourself in the hidden chamber from Dunwich. Bound by shackles, you see those you failed to save, bloodied and maimed. A creature with a man's face feeds from a corpse on the ground. The head of the corpse turns to face you, and a sharp pain stabs your heart."

Each investigator tests (X), where X is the number of names recorded under "Sacrificed to Yog-Sothoth." For each point an investigator fails by, that investigator takes 1 damage.

Each investigator who has not resigned is defeated and suffers 1 physical trauma.

If Hunting Horror is in play, add 1 doom to it.

If Hunting Horror is not in play, search the encounter deck, discard pile, and the void for Hunting Horror and spawn it in Museum Halls, if able. Shuffle the encounter discard pile into the encounter deck.

If there are 3 or more potential sacrifices, choose one of them at random and place it underneath the agenda deck, without looking at it.

Shuffle the encounter discard pile into the encounter deck.

Spawn 1 of the set-aside Brood of Yog-Sothoth enemies at a random location, if able.

Revelation - Spawn the set-aside Yog-Sothoth enemy at The Edge of the Universe. If The Edge of the Universe is not in play, spawn it in Another Dimension, instead. Advance to agenda 4a.

Remove each of the two leftmost locations from the game (or place it in the victory display if either one has Victory X and no clues on it). Each investigator at those locations is defeated. Each enemy and asset at those locations is discarded.

Discard all clues controlled by the investigators.

Shuffle the encounter discard pile into the encounter deck. If there is a set-aside Brood of Yog-Sothoth, the lead investigator reads the following (out loud):

Bleak storm clouds churn overhead and a blanket of rain pelts the countryside. As the downpour grows in intensity, you take refuge in a half-ruined shack nearby. There is a flash of lightning, and in the brief illumination, you spot the outline of something large in the rain. Without warning, the distant trees bend, though nothing seems to be bending them. Moments later, a force with the strength of a truck crashes into your refuge.

Spawn 1 of the set-aside Brood of Yog-Sothoth enemies at the lead investigator's location, if able. Then, each investigator at that location tests (4). The newly spawned Brood of Yog-Sothoth makes an attack against each investigator who fails this skill test.

In player order, Yog-Sothoth attacks each investigator in play, regardless of Yog-Sothoth's current location. Then, flip this agenda back to its "a" side.

If the Dormitories location is not in play, put it into play.

If The Experiment is in play, move it 1 location towards the Dormitories.

If The Experiment is not in play, spawn it in the Science Building.
