Perez-Toscano-Zelenetzky

Perez-Toscano-Zelenetzky,commonly known as PTZ,is a construction company operating during the Third Tiberium War. It acquired the contract from GDI to keep Tiberium spreading or entering buildings.

Supposedly working with state-of-the-art technology, there have been incidents in which PTZ made-buildings have malfunctioned. From a report from W3N reporter Annabella Wu, one housing building's automatic shutter system failed to work.
