4. Nuketown Is Crammed Full Of Easter Eggs

Like many developers, the teams behind the Call of Duty series are clearly fond of easter eggs and hidden secrets. However, the popular Black Ops level Nuketown has to be the most secret-filled multiplayer map of all time. Almost every facet of the map has some sort of easter egg hidden away, or contains a reference to something from popular controller. It's well known that the entire map is a homage to the infamous 'fridge scene' from Indiana Jones and the Kingdom of the Crystal Skull, as confirmed by the developers. Here's some secrets that you might not have noticed though: There's a hidden pathway linking the gardens of the houses, only accessible by the RC-XDs There's a Doomsday Clock outside the map, which also counts down the minutes remaining in the match. An exact replica of the Brady Bunch house can be seen just outside the map constraints There's a weird looking pink truck with the words "Replace Me!" written on its side. The "Welcome to Nuketown" sign displays the current number of players in the match. Our favourite easter egg though, involves a challenge regarding the mannequins scattered around the map. If players are able to shoot the heads off every mannequin within 15 seconds, then the Rolling Stones song "Sympathy for the Devil" will start playing.
