The levels featuring darkness or fog events make the game unplayable for those with visual impairments or eye conditions. Some solutions would be an accessibility menu toggle to disable these effects. This could also disable the special condition reward for those missions for those who have the options enabled.
Alternatives include a quick play filter to ensure the player can manually opt out of these missions, or a high-contrast mode. (which isn’t bound to work as well as the other two, but is still within the spirit of the game I guess.)
