Undead Corridor is a survival horror adventure. It throws you into dark, narrow corridors. The undead completely overwhelm the space. Your main objective is to clear these zombie-infested halls. You must push back the tide using your limited resources.
The game is built to challenge your limits. The horde gets faster and much more aggressive the longer you operate inside the building. This pressure means you have to adapt your strategy instantly while on the move, preventing you from ever settling into a fixed plan.

The game tracks several key statistics to measure your mastery. Your performance is measured by Corridor cleared, Kills, and Best result. The game uses distinct footsteps to build tension. You must pay close attention to these sound cues. You can anticipate incoming threats. You will not be surprised by the narrow corridors.
Stay mobile to avoid getting surrounded by the rapidly increasing horde. Movement is often your best defense.
Conserve your ammunition, especially early in the run. You will need every bullet when the enemy numbers multiply later.
You must prioritize quick takedowns. Eliminating an enemy fast reduces its chance to multiply the threat.
Undead Corridor is an intense survival game. It features multiple environments, such as the Hospital and Corridors. Try to survive the endless waves!
