How to play Nuclear Nightmare 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 Nuclear Nightmare handler
In Nucleus Co-op, search the Hub for Nuclear Nightmare and install its handler, or download the handler file from this page and drop it on the Nucleus window. Then show Nucleus where Nuclear Nightmare is installed.
Take a seat
Each player joins with their own keyboard and mouse and takes a spot on the screen. Pick a layout that fits your players.
Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.
Launch and connect
Press Launch: Nucleus opens one copy of Nuclear Nightmare 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.

it works perfectly for two keyboards and 2 mouse, can we get a support for the controllers please as playing with a friend through keyboard and mouse is not that good as small controllers in hands !
Unfortunately the game itself does not support gamepads. You'll have to ask the developers of Nuclear Nightmare for that.
