About this game
Black Fog is a survival horror with narrative elements, following the story of Kat and Eleanor, two ex-band members who haven't spoken in over two years. When a dark fog infused with a deadly neurotoxin encompasses the nation, Kat is inflicted with rampant hallucinations, unable to discern what is real, and what is not.
Throughout the night, you'll play as Kat while she attempts to survive an onslaught of dangerous manifestations. Various hallucinations will appear and distort the surrounding house. You will need to photograph them to stay alive, or else they will rapidly raise your anxiety to lethal heights. Alongside hallucinations, other entities will appear that will attempt to let toxins into the house, short circuit the power, and even attack you directly. Survive for 2 in-game hours until Eleanor arrives to drive you to safety.
Black Fog contains fully voiced story cutscenes, but the game can be played without them. Higher difficulties are available which will significantly increase the rate of hallucinations and enemy activity. With over 200+ hallucinations to find and fully random entity behaviour, each playthrough will not be the same as the last.

Minor Fix 1.04
Potentially fixed issues regarding a broken player state on loading previous saves. This fix is aimed at losing access to functions such as the smartphone.Potentially fixed issues where loading a save from the first save-point results in all items disappearing. Items may not be in the same place as before, but will now at least be guaranteed to spawn somewhere.Currently known issues are the stated issue where items do not retain their location at the first save-point in the game alongside some other UI scaling issues at varying resolutions. I am currently dedicating my time towards fixing game-breaking bugs as soon as i find out about them.For now, if you encounter any soft-locking bugs, please restart the application, as that seems to fix the majority of issues. I apologize for the inconvenience this may cause as I continue to discover bugs.Read full article on Community Announcements (polaris)AnnouncementsOfficial
