I remember seeing a screenshot for a certain map but I don't remember the name of it, nor do I know its gametype. I've been browsing the timeline for a few hours and haven't been able to find it so I'm asking anybody who reads this, who may know what I'm looking for.

Screenshot description (from memory): A close up of a door with olive colored fog.

If your browsing history hasn't been cleared, you could check that; if you recall roughly what day you saw this map.

I couldn't find a screenshot that matched your description, but the closest one (although not olive colored) I would guess it to be is: lvlworld.com/review/id:243

I don't actually remember whether or not there actually was fog, but I do remember the screenshot being in front of a doorway really close up. It may be a difficult map to find since most people don't find it to be all that striking.

I remember something like that, a red door. Maybe the map comes to my mind soon...
