NDI is a fictitious label used in the Uncharted series. NDI probably stands for Naughty Dog Industries and can be spotted on various objects, clothing and characters in the Uncharted games.

AppearancesEdit

• Nathan Drake - On the back of Nate's gun holster is an imprinted "NDI" along with a decorative circle around it.

• Harry Flynn - If you look closely at the top right of Flynn's shirt during the first flashback of Chapter 1 - A Rock and a Hard Place, you can notice a design with "NDI" at the bottom.

• Mk-NDI - The "NDI" in the name of the grenades is one of the more prominent uses of this easter egg.

• Parachute - If you look closely at Nathan's parachute from Uncharted: Drake's Fortune, the easter egg can be spotted
• London Restroom - In the one of The Pelicann's stalls, a sticker that says NDI can be seen.
• Storage Container - In Chapter 13 - Rough Seas, one of the storage containers has NDI on it. The same storage container also appears in the Graveyard multiplayer map.
