Everyone receives the same new z0mbies case at midnight Eastern. A morning survey maps a 6-by-6 or 7-by-7 building, showing the units that turned before the snapshot and those that survived.
The daily case is free, needs no signup, and stays separate from the 50-case Bureau campaign.
Autopsy a unit to read the night it turned. Every result narrows the possible origin because turn nights move outward through open rooms, slower barricaded doors, and paired air vents. The autopsy that reads night 0 identifies patient zero and closes the case.
Each day provides one limited autopsy bank. Run out before finding the origin and the case goes cold, then the reveal shows the complete spread.
Close cases on consecutive days to build a streak and climb the daily leaderboard. Solving at or under par earns a clean-read marker, and spoiler-free sharing shows how the investigation went without revealing the board.
Yes. The daily case, streaks, service record, and leaderboard are free to play.

No. You can play right away. Signing in keeps your streak and service record across devices.
