About 13 Masca

13 Masca is an investigation and survival game in which you examine 13 different individuals, identify those who seem suspicious and choose one to expel. You have 295 seconds to investigate. Of the four suspicious individuals, only one is the correct choice.

Investigate and choose

After the investigation, you select someone to expel and verify your choice through CCTV. If you choose correctly, they leave without incident. If you are wrong, something strange happens: the person transforms into a monster and roams the enclosed facility.

Escape the monster

When the person turns into a monster, you must leave the CCTV room and run. To escape, survive until a beam of light appears over an escape pit; entering the pit before the light appears ends the game.

If you survive, the day repeats, giving you another chance to narrow down the correct answer. If the monster catches you, or you fall into the pit too early, the game ends and the correct answer changes. When you make a wrong choice, you can observe the monster’s traits and focus on surviving as long as possible.
