The Great Clock's Mekanism has been dismantled by the Mekanotoks. Your goal? Rebuild it. In order to achieve this, you will need to find the necessary parts and reconstruct the technical plan. Infiltrate the Mekanism to restart the 6 engine rooms and reach the Cervomotor. To do this, nothing could be simpler: in each solved room, steal what you can from these crazy people to carry out your project: repair the Great Clock. You will have to undertake, play with subtlety and inventiveness and show unlimited motivation! If you succeed, you will reach the Cervomotor and can attempt to restart the Great Clock. But be careful, you could be trapped in Mekanism. The gears, restarting at full speed, can no longer be borrowed... if you want to escape in time, you will have to build your own exit door!
