Kletka

What works

With Nucleus Co-op, up to 6 players can play Kletka together on one PC, each in their own part of the screen, with controllers, keyboard and mouse or several keyboards and mice. The free community handler “KLETKA” by Zensuu does the setup and was checked by hub moderators: version 1, updated 21 Jul 2025. Kletka is an adventure and indie game from 2026.

How to play Kletka split screen on PC

1. 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.

   Download Nucleus Co-op

2. Install the Kletka handler

   In Nucleus Co-op, search the Hub for Kletka and install its handler, or download the handler file from this page and drop it on the Nucleus window. Then show Nucleus where Kletka is installed.

3. 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.

   Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.

4. Launch and connect

   Press Launch: Nucleus opens one copy of Kletka 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.
