Offensive Timing
Trigger reactor while crewmates are mid-way through long tasks on the opposite side of the map. The forced sprint scrambles coordination and drains the meeting timer if players stop to argue about direction.
Combine the sabotage with a door lock to split responders. One impostor escorts the first responder while the other finishes the job at the panel, creating opportunities for pocket kills.
Defensive Assignments
Crewmates should pre-assign two responders every round. When reactor starts blaring, those players move instantly while others continue tasks or guard hallways. The clarity prevents pileups and reduces friendly fire accusations.
Consider holding an emergency meeting immediately after a suspicious reactor if you notice role swaps or odd pathing. Fast discussion can stop impostors from leveraging the chaos.
Swap Awareness
Reactor swaps are dangerous because they relocate players while the timer ticks down. Count to three after the swap to make sure both panels are still covered. If not, rotate replacements quickly rather than blaming teammates.
Impostors should fake panic by lingering near the reactor entrance, then dart in once someone else clears the sabotage. The improved alibi is often worth sacrificing the kill.
