Red Faction: Guerilla easter egg
In the Museum Of Flight in the Museum District, go upstairs all the way and walk down the skywalk here. Note: You also must go here for a Ronin mission. Once up here, walk around looking up at the ceiling. You will eventually see a ship model up on the ceiling. This is a model EDF ship, the "Assault Aircraft - AAX" built by Ultor and to be used in the upcoming Red Faction: Guerilla game.
