In Manhunt, there is a magazine stand in Barcelona that features advertisements. One magazine in the middle of the stand, titled 'VG AM ES', features a scene in which a KPR transport helicopter gets caught in a large propane tank explosion. This references a scene from Operation Blockbuster, the first mission in Fallen Nation.

Gilman HQ Edit
There are two Easter Eggs in Mission 1: Infiltration and Mission 3: Mainframe. Both of these missions are in Chapter 6: Gilman HQ.
In Mission 1, after the Gilman Elite gets sniped by Sophie, there's a meeting room with a very long table and at the end of the room is an ammo box. In front of the supplies box is a computer and if the player hears carefully, it says "This is Commander Kal Wardin. N.O.V.A. Identification Number: 65D1--". This is a reference to a N.O.V.A. 3 campaign scene when Kal Wardin is suck in a building packed with Volterites along with his ally in Level 1: Homecoming. N.O.V.A. 3 is another First Person Shooter game by Gameloft but instead based on a futuristic background.
In Mission 3, after entering the security entrance, there's an office room to the player's left and inside is another ammo box. Next to it is a desk with a desktop computer and if the player hears closely, it will say "Wardin to Actual, please respond", "Yelena, do you read me?", and "Damn". These too are lines from Kal Wardin, who is a protagonist in the N.O.V.A. series.
Gangstar Vegas Edit
While joining a VIP match, an image is displayed in the background. This image contains a Gangstar Vegas poster on it.
In Mission 4: Getaway of Chapter 3: Downtown, there a car who's license plate reads ASPHALT and underneath it is GAMELOFT. This is a reference to a street racing series called Asphalt which is also developed by Gameloft.
Hidden Message Edit
On the multiplayer map Streets, a writing can be found at the entrance of the building. It is marked in blood and reads: "Though how I make my points not subtle, I dare you to find a better rebuttal!"
