get ready for hard mode

Necroboomicon is the first expansion to Two Rooms and a Boom, the party game that is always a blast. Think of it as Two Rooms and a Boom on HARD MODE!

We wanted to make our first expansion special so we focused on four things that we thought would make the game incredibly fun for old fans and new fans alike:

  • 10 All-New terrifying Character Cards inspired by the master of horror, H.P. Lovecraft.
  • Enhanced tension and play for seasoned Boomers.
  • Introduces and encourages color sharing when playing with fewer than 11 players.
  • Specifically designed to make Two Rooms just as fun with few players. Only have 6 players? NO PROBLEM!
  • Check out our awesome new Necroboomicon themed playsets!
“Highly recommended, this is the expansion I was waiting for. I can’t recommend it enough.”

How to Play

In Two Rooms and a Boom there are 2 teams and 2 rooms. The 2 teams are the Blue Team and the Red Team. The Blue Team has a President. The Red Team has a Bomber. Players are first equally distributed between 2 separate playing areas (usually
2 separate rooms) and then each player is randomly dealt a facedown character card.

Players play the game by saying what they want in order to select a leader for their room. The leader chooses hostages (players who will be sent to the other room at the end of the round).

The game consists of 3 timed rounds. Each round is shorter than the previous round. At the end of each round, the hostages selected by the leaders will be traded into opposing rooms.

The game ends after the last hostage exchange.

Everyone reveals their card. If Red Team’s Bomber is in the same room as the President, then the Red Team wins. Otherwise the Blue Team wins.
