Description
This is expansion pack #3 of the Doomsday Diaries | A murder mystery party game. Instantly downloadable expansion pack. This includes materials for 8 additional optional players (4F, 4M) and 4 expandable teams of duplicate, non-suspect players, which may be played in any combination in conjunction with the optional players in the main game or other packs.
The players will receive similar materials to the required players and will be unaware during the game play they were optional to the story.
We encourage you to play the packs in order, as the characters are added to the free invitation and pre-game lists in order. However, if you skip packs #1 or #2, just do not assign those characters to your players. Only use the host character list(s) for the packs you have purchased when assigning characters to your players. We will not refund an expansion pack if you skip a pack, as it can still be played.

There is a + because you can go over ~ 200 players, but don’t go much further than that.
What are expandable teams?
Expansion packs contain unique suspect character roles to add to the game, primarily seamlessly with the main game players. Some of our games will be able to cover large groups by using expandable teams. The expandable games will be designated within the description, the additional information section, and the host character lists for the main game and expansion packs. Doomsday Diaries has four expandable teams and can cover up to 200 players.
How it works:
A specified player(s) is designed to lead the (optional) team(s) during the game. Or, these characters may be played as solo players – adding any number of teams is entirely optional. But if you add teams – it’s as if the team leader got the invitation and decided to bring along friends, family, or colleagues (this varies). Assume (in the story) that these tag-along guests don't know anyone at the party. What would they speak to the other partygoers about? Well, they have a mutual friend (their team leader), so these players have game cards that contain their team leader's story.
For example, Esme Willow brings her staff members to the meeting with her. These can be players of either gender. The team players under Esme will have information regarding Esme’s storyline in their materials, which they can use to mingle and discuss with others (or they can play strictly as a team and stay with Esme).
The expandable players have duplicated cards, as you will download a file from your account and make copies for each team member with the downloadable version.
With the boxed version, you will receive teams prepared with the same type of materials as the rest of the players. However, the content on their cards will be duplicated, including instructions on how to play as their team and having information about their lead character and the story from their point of view. They are second-tier players because they do not have unique character names or stories, but play the game like everybody else. It’s best to assign your most shy/reserved players to these roles or players who are last-minute or unsure RSVPs. Do not assign your most outgoing and dependable players to these roles.
Do expandable team members get unique character names?
No, they will wear a name tag that has their general team name on it. We do not assign character names because once you do, they will be investigated during the investigation round, and this will eventually draw more attention to their second-tier status when you must instruct the players not to consider these characters – which you will inevitably have to do, as there’s not time to investigate 100+ suspects. If you tried that, your players will rage quit.
Therefore, it’s best to come clean from the start that they are non-suspect team members. On the other hand, they receive all the same game materials as everyone else; they investigate as individuals and submit guesses of whodunit, just like all the other players. They differ in that they don’t input new information into the game, except perhaps some insight into their lead character, who is a suspect in the murder.
