SECTOR 09
The phone line has been cut. The computer keeps receiving mail.
SECTOR 09 is a psychological horror puzzle game set entirely inside an old computer. Behind its familiar desktop lie corrupted files, forgotten conversations and a voice that seems to know who you are.
Explore abandoned applications, recover deleted messages and piece together the history of a family whose memories no longer agree. Follow clues across documents, decipher private notes and investigate processes that nobody remembers installing.
Some files offer answers. Others ask for permission.
As the story unfolds, you must decide which version of the past to trust, and what deserves to survive.

If a window calls you by name, that does not mean it knows you.

Hi! I would like to collaborate on the Spanish localization if you'd like. I'm an about-to-graduate translator looking forward to building my portfolio.
dude how do i download this
you can play it in browser, it's an HTML game, at the top of the page you can find the run game button
fair enough yeah, it's just that it was listed as downloadable on linux instead of just play in browser so i was hoping to download it for when i dont have internet lol
Yes, i think that's because i listed it wrong in the beginning, sorry for the misunderstanding
crazy
