Hi, over the years I have found concept art from the various artist that worked for the games that I can't figure out what they depict. As we have seen time and time before, sources tend to die out, making the images gone forever, so I decided to save them on my computer and now share them with you. I've have listed them here so we have the concepts archived until we figure out what they depict. I will likely add more and feel free to add any picture you might know of in the comments and I will add them to the list. All the file names are the original ones (I recall doing something similar way back and I can not remember why I had it deleted).

Game: BioShock
Artist: Scott Sinclair
Source: http://sincspace.com/
Speculation: From the site, we know that this is an enemy called Prepro. That's simple. Now all we gotta do is figure out what the hell that is! What I see is an "energy" enemy that constructs itself via random parts in it's surrounding. It's "anatomy" looks humanoid and is constructed by rubble, a lead pipe, parts of a Rosie Big Daddy, Rivet Gun and what seems to be one of the "circular light advertisement found by the Gatherer's Gardens", displaying the icon for the Photographer's Eye Gene Tonic. ???

Game: BioShock 2

Speculation: My first thought was Persephone as seen through the eyes of the Little Sister, everything is covered in cloth and it is the right color scheme, but something seems off...

Game: BioShock 2

Speculation: A hard one. I thought it was one of the structures that turn into the statue of Grace Holloway, Stanley Poole and Gilbert Alexander when the Little Sister sees it in Persephone, but honestly, it seems unlikely.

Game: BioShock Infinite
Artist: Chad King
Source: http://www.cking.co/#/concept/
Speculation: It seems to be an idea on the machine that keeps Columbia afloat or the Tesla Coil.

Game: BioShock Infinite
Artist: Chad King

Speculation: It looks like either a docking station or a "shield" the city is inside, maybe to protect from the elements?

Game: Minerva's Den
Artist: Devin St.Clair
Source: http://www.rapturearchives.org/php/concepts.php
Speculation: Likely the exterior of The Thinker level or part of the The Thinker's mainframe (note that nothing specifies that this is Minerva's Den, but it sure looks like it. It is BioShock 2 nonetheless).
