The game play is very simple, as a security guard you can only stay in their own security room, through the security cameras to view the situation in each room. The main screen is the security room, there is a TV (just can not watch), there are electric fans, left and right are two passageways with lights. If you find those "cute” animals to play with you, the door can be closed to prevent pushing down, but now this new office obviously lacks such protection measures. In addition, these little friends will also sneak in from different passages, but also deliberately let you hear the sound.

The game's choice of screen perspective can be said to be excellent, a room deliberately not let you look at the whole inside a screen, you need to keep sliding the screen to view the left and right sides of the channel.

When you feel that a partner crept in, all you can do is to bring up the mask to make yourself look exactly like them, so they will think you are one of them. Personally, I think the mask is the most successful setting in this game, a prop that seems to protect you, but is the biggest source of fear and unease.

You can get the image of the surveillance screen by clicking the bottom right of the game screen, which should be the whole surveillance system operation screen. By clicking on the different rooms on the floor plan can be switched to a different camera. Players need to do is to keep switching cameras to monitor the movement of each room.
