Corridor Z

Corridor Z is a side-scrolling endless runner with a zombie apocalypse skin, originally built for mobile and handheld platforms before landing on Steam. You play as a student sprinting through school corridors, vaulting obstacles and holding off the undead horde nipping at your heels. The core loop is exactly what you expect from the genre: run, jump, slide, survive a little longer than last time. There is a light progression layer with unlockable characters and some upgrade hooks, but the mechanical ceiling is low and you will likely see most of what the game offers within the first couple of hours. What works here is the premise's setting. A high school corridor full of lockers and flickering fluorescent lights is a genuinely underused backdrop for this genre, and Mass Creation squeezes some personality out of it. The character roster is small but varied enough to give early runs a slightly different feel, and the pacing of the zombie swarm behind you creates genuine tension in short bursts. For a runner, that is honestly the main job, and the game does it competently. What does not work as well is the transition from touchscreen to keyboard and mouse. The control scheme never fully shakes its mobile origins, and the PC version offers nothing that meaningfully justifies the port beyond the larger screen. There are no leaderboards to chase, no community hooks, and the content depth that keeps runners like this alive on phones simply is not here in enough quantity to hold a PC audience for long. The Mixed rating on Steam reflects real frustration, and most of that frustration is fair. If you are a genre completionist who specifically loves school-setting horror aesthetics and wants a short, low-stakes runner to fill twenty minutes, Corridor Z will scratch that itch without embarrassing itself. But if you are hoping for something with the craft and intentionality that makes a small indie worth returning to, this one does not quite have the soul for it. It is a competent mobile port dropped on a platform where competent is not really enough anymore. Kai, Scout Team
