While Call of Duty: Black Ops 1 (2010) does not natively support split-screen on PC, the community-developed Nucleus Co-op has made this classic couch co-op experience a reality. Using a dedicated handler, players can launch multiple instances of the game that sync for a seamless Zombies experience. Review: The PC Split-Screen Experience
For many, the lack of native split-screen was the only major flaw of the original PC release. This modded solution effectively bridges that gap.
Gameplay (9/10): Once configured, the gameplay is identical to the console version but with the added benefits of PC performance. You can run at higher resolutions and frame rates than the original PS3/Xbox 360 versions.
Ease of Use (6/10): It is not "plug-and-play." You must download the Nucleus Co-op app, install the specific Black Ops 1 handler, and follow a precise startup sequence (like pressing F2 to sync instances).
Compatibility (8/10): The handler works best with the Steam version of the game. It supports mixed inputs, allowing one person on keyboard/mouse while others use controllers.
Verdict: This is the definitive way to play BO1 Zombies today. It brings back the nostalgia of local co-op without the hardware limitations of 2010 consoles. How to Install & Set Up

Unlike its console counterparts, the PC version of Call of Duty: Black Ops 1 does not natively support split-screen out of the box for the Steam version. Enabling this feature requires modifying configuration files to unlock developer commands and properly mapping secondary input devices. This paper outlines the step-by-step process to enable two-player local cooperative play.
Unlike the console versions, the PC port of Call of Duty: Black Ops did not originally include native split-screen support for Zombies. However, thanks to community patches and configuration tweaks, you can play two-player split-screen on a single PC — with full controller + keyboard support.
Given the technical hurdles and potential for software to become outdated, achieving a stable split-screen experience in Black Ops 1 on PC can be difficult. Always ensure you're using legitimate copies of software and games, and be cautious with third-party tools to avoid security risks.
The Steam version does not have a "Local Play" button on the main menu. You must load into the mode directly via the console.
For the simplest experience:
✅ Use Plutonium – it’s free, legal (needs your game files), and includes split-screen with no extra hacking.
For pure Steam without third-party clients:
⚠️ Use the BO1 Split Screen Tool, but expect occasional bugs.
Officially, Black Ops 1 does not support split-screen on PC. However, you can achieve this using community-made tools like Nucleus Co-op, which essentially runs multiple instances of the game and syncs them for local play. Installation Guide: Nucleus Co-op Method
This is the most reliable way to play 2-player (or more) Zombies on a single PC.
Download Nucleus Co-op: Get the latest version from the Official GitHub or Splitscreen.me. Add the Game Handler: Open Nucleus Co-op and click Download Game Handlers.
Search for "Call of Duty: Black Ops" and download the script.
Note: Some versions (like Plutonium) might require a specific modded handler found via community guides. Link Your Game:
Click Search Game and point the app to your BlackOps.exe file (typically found in your Steam common/cod blackops folder). Configure Input & Screen:
Assign your controllers (gamepads) or keyboard/mouse to each player by dragging them to the split-screen layout. Set the number of players to 2 for Zombies in the settings. Launch & Sync: Press Play. Nucleus will open two separate game windows.
In the first window, go to Zombies > Find Match (or Private Match) and select a map.
Press the Start button or F2 (depending on the handler) to connect the second instance to the lobby. Alternative: Plutonium T5 Mod
If you want a more modernized experience with server browsers and custom mods, many players use the Plutonium T5 client.
Setup: Create a Plutonium account, download the launcher, and link it to your Black Ops 1 files.
Split-screen: You still generally need Nucleus Co-op alongside Plutonium to handle the multi-instance split-screen layout. Pro Tips for Performance
Window Management: Once the game starts, use Ctrl+Q to close all instances quickly.
Input Locking: If you are using a keyboard and mouse for one player, press the End key to lock the mouse to that specific game window.
Antivirus: Game handlers often trigger "false positive" virus warnings because they inject code to manage window positions; you may need to add an exception for Nucleus Co-op.
