Game: Call of Cthulhu — The Haunting (Quick-Start)

  • The video explains how to run the classic scenario “The Haunting”, a quick-start module reused across many editions.
  • It emphasizes a blend of horror, research, sudden violence, and potential insanity.
  • The approach is framed as “6 GM tips” to help smooth the experience for new players by tweaking the scenario.

Storyline Outline (What Happens in the Scenario)

Setup / Mission

  • Investigators are hired by Mr. Knott (owner of a potentially haunted property) to discover why people won’t live in his house.
  • The scenario includes pay ($20/day in the premise), but the GM advice is to give players a stronger personal stake than money alone.

Big Reveal / Antagonist

  • The previous tenant, Mr. Corbett, is concealed in the basement.
  • Corbett functions like an undead wizard/lich, tied to a cult called the Church of Contemplation.
  • Anyone who enters the house is targeted.
  • The core objective is to reach the basement and kill Corbett.

Win Condition

  • Success = get into the basement and kill Mr. Corbett.

Gameplay Highlights & GM Strategies / Key Tips

1) Improve Player Buy-In (Make It More Than “Random People Investigating”)

Instead of having investigators simply accept a generic job, the GM suggests using Mr. Knott’s leverage:

  • Employ blackmail, favors, or debt so the investigators must participate.
  • This also creates tension without requiring the party to be friends—everyone can share a link to the same threat.

Optional framing ideas:

  • Mr. Knott cannot personally go (e.g., wheelchair/casts from an accident), so he hires them as his “eyes and ears.”
  • Mr. Knott is a reckless rich playboy whose funds were cut off, forcing him to delegate the job.

2) Keep the Scenario “Research-First” (Teach Call of Cthulhu Gameplay)

Research is a central pillar of Call of Cthulhu. Suggested flow:

  • Players conduct inquiries first (e.g., libraries, interviews, records).
  • Then they proceed to the house.

Directing players without railroading:

  • Don’t let the house be the first thing they do.

  • Provide multiple credible “next steps” by offering reasons to go to other locations:

    • Sanitarium (last tenants / “Macarios”)
    • Hall of Records / archives (history and the Reverend behind Corbett’s estate)
    • Church of Contemplation (creepy location; can include set-piece moments)
    • Police / reporters (if you want leads through journalism or official channels)

This “bounce between locations” method builds knowledge and tension before violence.

3) Make the House Scarier and Fairer (Specific Scene Tweaks)

Window Writing Before the Bed Attack

In the well-known bed-attack scene:

  • Don’t only use sounds.
  • Instead, have scraped words appear on the window to imply Corbett’s agency.
  • Example word ideas mentioned:
    • “sucker”
    • “boo” was also tried by the speaker

Basement Navigation Clarity

A common new-player issue is missing a critical route:

  • Make it clear the basement is surprisingly small.
  • Point out why there’s one wooden wall segment where others are stone.
  • Help players understand they can go through/behind the wooden boards.

Make the Floating Knife Matter More

The knife is deadly but can be underwhelming in importance as written. Enhancement:

  • Make the knife act as a magic point drainer:
    • It deals no/low damage, but reduces Magic points instead.
    • When used against Corbett, it gradually reduces his Magic.
    • Describe visible effects (e.g., skin/tightness/dryness) to make the change obvious.

Goal:

  • Teach players that resources (Magic points) are mechanically and narratively important.
  • Turn the knife into a meaningful early “artifact.”

Reduce “Unfair Surprise” With Rats

The speaker finds the rat hazard too punishing as written (too many stacked surprises). Fairness method:

  • When players are knocking down/breaking the wooden wall that leads to rats, require a Listen check to notice danger.
  • If they succeed, grant a Dodge bonus die/benefit so they aren’t instantly ambushed without warning.

4) Handle Character Death Cleanly (Use Backup Investigators)

Don’t be afraid of character death—CoC is inherently deadly. For quick-start fun:

  • Prepare backup investigators ahead of time.

Instant replacement NPC ideas:

  • Mr. Knott’s butler (has access/lines; can rush in when screams happen)
  • A reporter who previously investigated the house
  • A police replacement (another officer/investigator if the PCs inform authorities)

Key requirement:

  • Have someone able to immediately enter via the basement door after an investigator dies.

5) Upgrade the Handout Experience

The official quick-start handouts are described as mostly text inbox-style. The video recommends a community-made handout pack:

  • “Cultist Armory” (very comprehensive)
    • Includes items like psychiatric reports, police raid reports, newspaper clippings, a death certificate, etc.

Cautions and adjustments:

  • Older, re-posted handouts may contain incorrect dates.
  • Consider trimming very long sections (e.g., huge police reports) so players aren’t overwhelmed.
  • The GM may avoid giving Corbett’s diary entries directly (they’re lengthy); instead provide “cliff notes.”

6) Use the Right Rule Documents (Edition/Version Pitfalls)

The speaker advises downloading both versions of the quick-start rules:

  • An older version that lacks certain elements (including pregenerated characters)
  • A newer version that includes pregenerated characters (“preens”) but removes the quick-start character generation system

If you don’t own the full core rulebook:

  • Having both sets ensures you can run the game using pregens or whichever character creation route you prefer.
