Zombie Panic Source

What is Zombie Panic Source?

Zombie Panic! Source is a multiplayer Half-Life 2 first-person shooter modification and features four modes of gameplay, Zombie Panic! Survival mode, Zombie Panic! Objective mode, Zombie Panic! Hardcore mode, and ZPA mode.


During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named hl2.exe. The setup package generally installs about 93 files and is usually about 79.84 MB (83,719,508 bytes).
