About This Game

In a world of beautiful silence, a killer named NULL lurks among you.

『Who's NULL?』 is an online social deduction game for 4–8 players, set in a liminal space.
In this world, other players appear only as glitchy silhouettes.
These figures flicker in and out of sight, making it difficult to tell who's who or where everyone is.
Your only clue to their identities is their unique footsteps.
Listen to the footsteps echoing through the silence and figure out who's nearby.

Roles

■ VISITOR

As a VISITOR, your goal is to escape from the strange world you've wandered into.
If even one of you escapes, you can destroy this strange world and rescue everyone else.

• Search the map for scattered shape pieces and fit them into the walls to complete each shape.
  
• Once all the shapes are completed, an exit will appear.
  
• If even one VISITOR escapes before time runs out, the VISITORS win.
  
• But beware: a killer named NULL is hiding among you.

■ NULL

As NULL, your goal is to kill the VISITORS and prevent anyone from escaping.

• Only NULL can run, allowing you to approach other players quickly.
  
• However, if someone hears you running, they might figure out who you are.
  
• You can also carry pieces alongside the VISITORS and pretend to help them.
  
• If no one escapes before time runs out, NULL wins.

Meetings

Meetings are held at regular intervals during exploration, bringing all players together.

You might not even realize someone has been killed until a meeting begins.

"Whose footsteps did you hear, and where?"
"Who was the last person in that room?"
"Who placed this piece?"

During meetings, you can listen to every player's footsteps as many times as you like.
Think back to the sounds you heard while exploring and compare them with what the other players say.

Vote to eliminate players you suspect of being NULL.
But eliminating an innocent teammate will make escaping that much harder.
