Gamers with keen eyes have spotted (via reddit) something interesting in a Max Payne 3 multiplayer map called Tiete River Docks. A small office located in one of the buildings has a bunch of photos pinned onto the wall containing four images of airplanes.
If you've paid any attention to the jet fighter in the Grand Theft Auto V trailer you'll notice some striking similarities. Notably, the fighter jet in the photos is identical to the one in the trailer.
This is just the sort of thing Rockstar would do, having embedded numerous easter eggs in all of its other games.
We'll just have to wait for the PC version of Max Payne 3 to come out (that's today, actually!) for a higher resolution screenshot.
