Split-screen games divide a single display so two or more players can share the same screen on one device, making them a staple of couch gaming. The format trades online separation for in-person company, letting friends or family play side by side in real time. Whether cooperating through the puzzles of It Takes Two or surviving together in Project Zomboid, split-screen titles prioritize local togetherness, shared laughs, and the immediacy of playing with someone right next to you.
