Roles

Three roles.
One truth.

The deck is intentionally biased against Workers. Without strict oversight, Sabotage is inevitable.

Worker

Labor for the good of the plant

Goal: Implement 5 Modernization blueprints or Terminate the Rat. You don't know who is sabotaging the work — rely on behavior and voting patterns.

Saboteur

Time to break the machines

Goal: Implement 6 Sabotage blueprints or appoint the Rat as Chief Engineer. You know the other Saboteurs and the Rat — but blend in.

The Rat

The secret leader of dissent

Goal: Bankrupt the company. If 3+ Modernizations are active and you become Chief Engineer — your team wins instantly! Avoid Termination!

Blueprint Deck

17 blueprints.
Two agendas.

The CEO reviews 3 blueprints each shift, discards 1, and passes 2 to the Chief Engineer, who implements 1. Watch what gets enacted.

Modernization — 5 needed

Workers win at 5 Modernizations

Sabotage — 6 needed

Saboteurs win at 6 Sabotages

Shift

Shift Formation Phase
+ Production Cycle.

Each round is called a Shift. Three failed shifts trigger Chaos on the Floor — a blueprint is auto-implemented and the downtime tracker resets.

Appointment

The current CEO nominates a candidate for Chief Engineer. Term-limited players are ineligible.

General Meeting

All players vote. Majority required to pass. A tie results in failure. Three consecutive failures trigger Chaos on the Floor.

Blueprint Archive

The CEO draws the top 3 blueprints, secretly discards 1, and passes the remaining 2 to the Chief Engineer. You can lie to them.

Chief Engineer's Workshop

The Chief Engineer chooses 1 of the 2 blueprints to implement. The other goes to the shredder. Veto Power may be requested if unlocked.

CEO Directive

Certain Sabotage milestones grant the CEO special authority. The directive is used immediately after the blueprint is enacted.

CEO Directives

Executive authority
grows with decay.

By implementing Sabotage blueprints, the CEO gains access to special directives based on the level of plant decay.

🔍

Personnel Audit

The CEO secretly checks a player's file — Worker or Saboteur. Each player can only be audited once. You may lie about the result.

📋
