About this game
The tubes are still on. The watchman is dead—the knife is still out.
Notary Block is a co-op suspense accusation horror for four to eight players, set in a Hong Kong twin-tower public-housing estate rebuilt from a real block. Stay alive in the blackout, turn the estate itself into evidence, and walk out through the ground gate—only if you cross it yourself.
What you do
Residents: hide, search, find bodies, hold a short meeting, vote. A vote that names the killer sheathes the knife and opens the gate—it is not a team victory. The watchman's keys open the same gate. You only got out if you walked through it yourself.
Killer: limited strikes, hide bodies, plant items, cut the main power, camp the gate. The fewer people who leave, the better your night.
How a round ends
The first resident through an open gate—or a correct vote—starts a forty-five-second sting. Then a personal night report for everyone: got out, died, or didn't leave. The first escape does not end the table.
The estate is the weapon
Grab and throw use real physics. Hidden bodies, blackouts, gated corridors, eyewitnesses and lies—accusations come from what happened on the floor, not from a case board. This is not stand-on-the-map-until-vote.
Who it's for
Four to eight on voice. About fifteen to twenty-five minutes per round. Traditional Chinese and English on the page; Cantonese-first in tone.

Solo practice can finally finish a night
Most of this build is fixing solo practice so it actually feels like a full round.A few things kept breaking the flow: the meeting UI was hard to read, the second swing after a meeting sometimes did nothing, and wiping out all the practice dummies still would not drop you into the night report. This update fixes that. Names are easier to read in the office meeting, voting works, and you can still strike after the meeting ends. If only two people are left, the game stops forcing another meeting. Clear the practice seats and you get the personal night report.Two smaller additions: killers get a short identity slip at the start, and solo players can switch resident/killer before F5 with F3 or the pause menu.Four to eight players is still friends-only on Steam. No public matchmaking.If you are on wishlist only, you will not see this until the next live build goes up.Drop a note in the community hub if something still feels off.ːzoteːRead full article on Community Announcements (zeroexezx)
