How to play Zombie Panic! Source split screen on PC
Get Nucleus Co-op
Download Nucleus Co-op, free for Windows 10 and 11, and unzip it into its own folder, for example C:\NucleusCo-op. There is no installer.
Keep it out of Program Files, your user folder and OneDrive.
Install the Zombie Panic! Source handler
In Nucleus Co-op, search the Hub for Zombie Panic! Source and install its handler, or download the handler file from this page and drop it on the Nucleus window. Then show Nucleus where Zombie Panic! Source is installed.
Take a seat
Each player presses a button on their own controller to join and takes a spot on the screen. Pick a layout that fits your players.
Launch and connect
Press Launch: Nucleus opens one copy of Zombie Panic! Source per player and lays the windows out on your screen. Then link them in game, usually one player hosts a LAN or online session and the others join it. The handler notes say how.
What you need
- A Windows 10 or 11 PC
Nucleus Co-op runs on Windows only. System requirements
