SCP - 914: The Clockworks (Beta Testing!)

Welcome to the SCP 914 test room. You can upgrade various items here, and you can see how the machine works. I created a series of card doors on a moving path. When the item goes past a door, a script will detect the items name. Then it will drop the old item, and it will open a separate door. The separate door will drop the upgraded item. Its a complex system.. I hope you like it! So far you can only upgrade cards and fire extinguishers.
