About 13 MASCA Steam Key:

Investigate the Unusual Individual Among 13 completely different individuals, identify those who seem… off. You have 295 seconds. Choose Someone to Expel Once the investigation ends, select one person you find suspicious and expel them. Verify Through CCTV Out of 4 suspicious individuals, only one is correct. If you chose correctly, they will leave without incident… But if you’re wrong… something strange will happen. Escape the Monster If something feels off, leave the CCTV room immediately and run! In this enclosed space, that person will turn into a monster and roam the facility. Survive long enough, and a beam of light will appear over an escape pit—your only way out. The Investigation Continues If you survive, the day will repeat, allowing you to gradually narrow down the correct answer. However, if you’re caught by the monster—or fall into the pit before the light appears— it’s game over, and the correct answer will change. So when you make the wrong choice, observe the monster’s traits and focus on surviving as long as possible.
