Among Us WIP

This is a start of a boardgame experiment for my kid using the Traitor mechanic. I don't want it to be similar to Secret Hitler, Mafia, or Werewolf because it needs to work for just 1 to 3 players if necessary. It also needs to be lighter and with less fiddly bits than games listed here; https://boardgamegeek.com/thread/1657498/games-traitor-mechanic

Prototype Art

Here's the pieces I printed and painted. The design is from Thingiverse.com by usre swlhonda at https://www.thingiverse.com/thing:4635009

Sample hall with six of the Among Us crew members. I will eventually create a total of 12 and include the alien impostor variations.

Game Design Outline

These are my current thoughts on how the game should operate. I'm quite sure that the final design will be very different.

Overview

1. This is meant to be a 2 to 4 player game. It has player elimination.
2. Each player controls a competing Team of Science and Engineering crew comprised of 3 to 5 members. One of which is an agitator known to that player but not by the other players.
3. Work environment is a Deep Space Research Facility on the surface of Europa with competing budgets all reporting to the Corporate Director.
4. Goal of the game is to sabotage the efforts of the other players while promoting own team.

Elements

1. There will be a 3D map with multiple Facility Areas, and a Task Deck. 
2. Facility Areas include several Connecting Hallways, Recreation Rooms, and Dining Area in addition to Med Bay, Engineering Deck, Command Center, Data Bay, Crew Quarters, Docking Area, Engine Room, Weapons Bay, Bio-sciences Bay, and Hazardous Waste Container. There's a different ability for each section. 

Preparation

1. The Task Deck is stuffed with actions which include cards for Sabotage and Kill.
2. During the Initiative Phase determining Crew Order.
3. Draw one card from the Task Deck for each crew a player controls to an hand. Examine the cards and assign them face-down to each crew controlled as part of its Action buffer.
4. During the Exchange Phase, crew within the same Facility Area may exchange cards freely. Sabotage and Kill cards may be given to other player's Crew's buffer face-down. Do not look at yet.
5. During the Activity Phase, in Crew Order, navigate crew to each Research Area and place a known card from their hand or one drawn at random from the Action buffer for that crew face-down at that terminal.
6. Crews without items in their Action buffer can wander to adjacent the Facility Areas.
7. During the Wander Phase, each Crew may continue to move about spend time in their present Area.
8. During the Inspection Phase, each Area's terminal with Task Cards face-down has them revealed. If there is Sabotage card; that Area loses ability and it affects the entire Research Facility.
9. If there is a Kill card; one crew in that Area, per the Crew order, is injured and goes to the Med Bay.
10. If there are are multiple Kill or Sabotage cards; the damage is increased.
11. During the Vote Phase, players nominate Suspect crew to be Spaced! Suspect crew are those which remained are in the Area where a Sabotage or Kill card was revealed.
12. Crew which are Spaced! are removed from play. A player with no remaining Crew is removed from play.
13. Game continues until just one Team remains in play.
    

Concerns

I want to use Victory Points for placing Tasks, and for remaining near Facility Areas during the Inspection Phase. I want to allow players which have been eliminated from play to continue scoring VP. I want the winner of the game to have the highest VP.

An idea could be to place Task cards which build sets. Each Team is given a secret favored Set type, and each Task card has different colors. Scoring the most favored sets gives VP at the end of the game.
