New York Times Easter egg
From Halopedia, the Halo wiki

TheNew York Times is anEaster egg inHalo 3: ODST. Throughout the game, papers and other various detritus litter the ground. Although most of these items are completely indecipherable, one is a newspaper bearing the partially obscured headline:
ARMISTICE (SIGNED, END OF) THE WAR!BERLIN SEIZED BY REVOLUTIONISTS;NEW CHANCELLOR BEGS FOR ORDER;OUSTED KAISER FLEES TO HOLLAND
Unlike most Easter eggs found in theHalo games, this newspaper story is not fictional. It is in reality the front page of theNew York Times from November 11, 1918, announcing the end of the First World War.[1]
Location[edit]
Although the newspaper can be found throughout the game, it is perhaps most easily viewed onNMPD HQ, as it appears in a fully lit area. Four copies of the paper can be found in the room in whichEdward Buck says, "Grab some ammo, Romeo. These boys won't need it." One is inside the desk in the center of the room, near a dead NMPD officer's left foot. A second is to the officer's right, near a chair; in theMaster Chief Collection version of the game, a sniper rifle is pointing directly at it. A third is to the far right of the room, near a dead NMPD officer, a dead Grunt, and a large blood stain on the floor. The final copy is on the left side of the room near the far ACchatter console.
