Steamの詳しい説明を読む
TWO PLAYERS. ONE BODY.
Experiment 15 is a two-player online co-op psychological horror puzzle game where you and your partner share control of a single body.
One of you controls the body.
The other controls the mind.
You will need to communicate, cooperate, and rely on each other's perception to survive a series of increasingly disturbing experiments.
SHARE CONTROL
Neither player has complete control.
While one player is responsible for movement and physical interaction, the other controls where you look and how you perceive the environment.
Something one of you can see may be completely invisible to the other.
Your greatest advantage is also your greatest weakness: you need each other.
SOLVE EXPERIMENTS TOGETHER
Every experiment introduces new rules and challenges the way you communicate.
Manipulate objects, coordinate movement, observe your surroundings, and combine the information available to each player to find a way forward.
Sometimes the solution depends on what you can see.
Sometimes it depends on what your partner can't.
SOMETHING IS WRONG HERE
You were brought here to complete Experiment 15.
At least, that's what you've been told.
As you progress deeper into the facility, fragments of the past begin to surface. Strange messages, forgotten memories, and increasingly unsettling experiments raise a simple question:
Why are you really here?
