Calling all units! A serious theft has occurred!
The thief is hiding in one of the buildings. Police helicopters are patrolling between buildings to track and stop the escape. Will the police arrest the thief, or will the thief escape?
In more detail, at the start of the game the board is set up with 25 3D buildings that can be lifted to put the thief's car under. In the thief's turn all police players must close their eyes while the thief moves their car to under an adjacent building. Then in the police turn they open their eyes and can perform 1 of 2 possible actions each: move or search. While moving the helicopter moves to an adjacent crossing. While searching the helicopter may look under an adjacent building.
The police players collectively win if they find the thief within the 11 rounds. The thief wins if they stay hidden for 11 rounds.
