How to Play

Slenderman Horror Story MadHouse is designed to be both accessible and intense. Here's how you'll navigate the harrowing experience:

  • Movement and Actions: Use the WASD keys to move your character around. Left Shift will let you sprint, and Left Ctrl will let you crouch to avoid detection. Press X to go prone for a momentary hiding spot, or jump with Space to leap over obstacles or escape a close encounter.

  • Combat: Engage with the environment using your mouse. Click with the left mouse button to fire your weapon, or right-click to aim and block incoming attacks. In a pinch, you can reload your weapon with R, toss a grenade with G, or activate bullet time for a brief window of safety with T.

  • Puzzles and Challenges: Your escape will rely on solving intricate puzzles. Look for clues, interact with objects, and use items you find to progress. Be vigilant; the lines between reality and illusion are increasingly blurred.

  • Mental Patients: As you navigate the madhouse, you'll encounter a variety of psychiatric patients who pose their own set of challenges. Keep your wits about you and your weapon ready.

  • Pause Menu: If you need a moment to catch your breath or just want to take a break, press Esc or Tab to pause the game.
