Hmmsim Metro Patch Notes — January 29, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Hello.
In this update, passengers and CCTV have been added.
Passengers
Moving passengers have been added to stations and trains.
Passengers board or alight depending on the situation, showing different levels of crowding based on time of day, station, and direction.
CCTV
Platform CCTV monitors have been added, allowing you to check passengers boarding or alighting.
They are also displayed on the CCTV monitor in the one-handle train cab.
Sounds
Ambient sounds have been added to outdoor areas and tunnels, and traffic driving sounds have been changed.
When windows or doors are opened inside the train, outside sounds can now be heard.
Settings
Passenger density and CCTV settings have been added.
(If your PC has sufficient performance, it is recommended to set passenger density to the maximum.)
Environment volume and train volume settings have been added.
A display showing the current value of sliders has been added.
Other
Doors will now close only when the departure time is reached.
An issue where train doors appeared blocked has been fixed.
The route from Kwangwoon Univ. Station platforms 6 and 7 toward Seokgye Station has been changed.
AS pressure and pneumatic doors are now linked to MR pressure, and the rate of BC pressure increase and decrease has been limited.
At the early stage of development, I did not plan to implement passenger features, as I felt they would be difficult to realize naturally.
Due to many requests over time, I developed the passenger feature, but there are clear limitations to what can be expressed through solo development.
I believe that further improving the modeling and animation, or implementing more natural movements, is realistically difficult.
Thank you.
