My Sudden But Inevitable Betrayal
“SOMETIMES, THEY COME BACK.”
I’ve heard that a lot. I didn’t think it’d be me, of course. In 2003, my last project at Wizards of the
Coast was developing Bruce Glassco’s game “The House on the Hill.” I loved the game. It was my team’s
solution to a single player overlording a cooperative game. We made you care about your character, and
fear letting someone else get all the good stuff. If you could be betrayed, you’d play cooperatively, but
think individually.
It was a great concept, and it got the best team.
Hasbro’s Rob Daviau crafted the draft version from
Bruce’s original manuscript. Then I put together a
rock star crew—Bruce Cordell, Teeuwynn Woodruff,
Bill McQuillan, and many others—to make a rock star
game. We called it Betrayal at House on the Hill
®
.
With Betrayal in the books, I left to start my
company, Lone Shark Games, right at the end of the
design process. I figured that’d be the last I’d hear
of the game.
Then something happened. Right around the
release of the 2nd Edition in 2010, people started
talking about Betrayal a ton. They’d come up
and tell me that it was their favorite game, that
it changed their lives. People like Cards Against
Humanity co-creator Max Temkin, cartoonist
Pendleton Ward, and Doubleclicks singer Angela
M. Webber. It influenced the work of fans like
videogame designer Zoë Quinn and Dead of Winter
designer Jonathan Gilmour. I hired two of Betrayal’s
biggest fans, Elisa Teague and Liz Spain, to be game
designers on my team.
And at every convention, in every panel Q&A
session, I would get asked one question:
“Would you ever consider doing more Betrayal?”
“You should ask Wizards,” I’d say, and change
the subject. I understood where they came from.
Betrayal is episodic, and everyone wants new
episodes of their favorite show. But actually making
new episodes was unlikely to happen. In a practical
sense, I put the thought out of my mind. I hoped I’d
get another shot at it, but the real world stands in
the way of such things. So, I kept designing new
games.
While making the Apocrypha Adventure Card
Game, I described it as “the spiritual successor to
Betrayal.” These were bold words. As we made our
modern horror game shine, we revisited Betrayal to
remind ourselves what made it tick. And we started
thinking of all new ideas for it. Ideas which would
go nowhere unless . . .
“Hey Mike, do you want to do more Betrayal?”
The voice on the phone was Mike Mearls, head of
R&D for Dungeons & Dragons
®
. Wizards wanted to
create an expansion for Betrayal, and because of my
history with the game, they thought of me first. It
was the day after my birthday. I assured Mike that
yes, I’d like that very much.
So as we were developing one modern horror
game, we began—in secret and in the shadows—
to develop a second. We kept it to ourselves,
codenaming it “Project Riboflavin” (aka “B2”). I
invited all those friends who told me they loved
Betrayal to write haunts. Rob, Elisa, and Liz joined
me on the core team. Some of their stuff was mind-
bogglingly strange. All of it was great.
We added cards, tokens, and rooms that led you
all around the inner spaces of the house. And we
put a roof on the house, because every house needs
a roof.
So yeah, when someone says “sometimes they
come back,” you should listen.

NEW CARDS AND TILES
At the start of the game, shuffle the new
event cards, item cards, omen cards,
and room tiles in with the ones from the
base game.
GLOSSARY UPDATE
Companion: The Cat, Dog, Girl, and
Madman are companions.
Outside: When a haunt references
outside rooms, this includes the Balcony,
Conservatory, Gardens, Graveyard, Patio,
Roof Landing, Solarium, Tower, Tree House,
and Widow’s Walk.
Weapon: The Axe, Blood Dagger,
Boomstick, Chainsaw, Revolver, Sacrificial
Dagger, and Spear are weapons.
Window: The Bedroom, Chapel, Dining
Room, Drawing Room, Grand Staircase,
Master Bedroom, and Sewing Room
have windows.
THE ROOF
The roof is a new floor. When you start
play, put the Roof Landing in play. As noted
on that tile, when you discover a room on
the roof, use the first room tile that has
either the roof or the upper floor on the
back. The roof is not a second upper floor;
for example, the Mystic Elevator only goes
to the roof when you roll a 4 and choose
the roof.
LANDINGS
Several tiles are referred to as landings
in this expansion. The landings are the
Basement Landing, Grand Staircase/Foyer/
Entrance Hall (or any room of it), Upper
Landing, and Roof Landing.
NEW ROOM SYMBOLS
The
symbol on a room tile means that
the room has a dumbwaiter. You can move from that room to the landing either one floor up or one floor down, assuming such a floor exists, by spending 1 additional space of movement. This requirement is in addition to any other such requirements,
such as being in a room with an opponent.
So, if the Menagerie were on the basement,
you could move from it to the Foyer by
spending 2 spaces of movement; if it
were on the ground floor, you could move
from it to the Basement Landing or the
Upper Landing by spending 2 spaces
of movement. If you don’t have enough
Speed to move that far, you can’t use the
dumbwaiter.
The
? means you draw the top card of a stack
of your choice when you discover the room.
EXPLORER TOKENS
The 36 circular explorer tokens, 6 of each
color, bearing each explorer’s face indicate
possession or completion of something by
that explorer. When you use the Chapel,
Gymnasium, Larder, Library, Menagerie,
or Study’s power to gain a trait, leave your
colored explorer token on the room tile.
When you are in that room thereafter, you
may not use that room’s power to gain a trait.
These tokens may be used in haunts as well.
OBSTACLE AND LOCK TOKENS
The Obstacle and Lock tokens represent
barriers that explorers will need to do
certain actions to get through. Traitors and
monsters ignore these tokens unless the
haunt says otherwise.

Survival, If they have not,
ignore the haunt roll.
TRIGGERING THE HAUNT
When you trigger the haunt, use the new haunt chart below.
* If two explorers tie, and one of them is the haunt revealer, choose the haunt revealer.
If neither player is the haunt revealer, choose the one who’s closest to the left of the haunt revealer.
POSSIBLE
FLOORS
OPTIONAL RULE: PLAYING
ONLY NEW HAUNTS
If you trigger a haunt with an omen from
the base game in a room from the base
game, you will get a haunt from the base
set. If you only want to play a haunt
from this expansion, you may discard
the omen and draw and discard omens
until you get one from this expansion. Or
you may discard the room tile and draw
and discard rooms until you get an omen
room for this floor from this expansion. If
all of those omens or rooms are in play,
choose the last one that entered play.
