- A pink box of donuts can be found in the building near the Militia spawn. This is a reference to "The Simpsons" due to the fact Homer Simpson works in a Power Plant and often eats donuts at his workspace.
- A film poster with the title "Meltdown" and an image of one of this map's cooling towers can be found throughout the campaign. Like most film posters it contains developer references, in this case level designer Adam Hoggatt amongst others.
