BioShock concept art reveals what Big Daddies look like under their helmets

Have you ever seen a Big Daddy from BioShock without his helmet on? If not, consider this the first/worst day of the rest of your life. PC Gamer writer Andy Kelly made the grim discovery and shared it on his Twitter account, spreading far and wide the image which the BioShock fan wiki attributes to former Irrational Games senior concept artist Robb Waters. The BioShock games deliberately conceal what Big Daddies look like under the hulking frame of their metal dive suits, but they imply that the maintenance personnel turned Little Sister guardians have changed a lot from the people they once were.
