Perez-Toscano-Zelenetzky, commonly known as PTZ, is a construction company appering in the Tiberium Wars novel.

BackgroundEdit

The company won a contract from GDI to keep Tiberium from 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.
