Nearly all Unreal Engine 3 games use flash for their hud. MOST AAA games recently use flash for their hud/menu's via some framework/library I can't think of right now however it's widely used. Rage, Dead Space, Bulletstorm, Crysis 2, and many more games use Flash for their hud/menu's. Flash gives the artist more control over their gui/hud. More 3d effects, shadows, etc. 'Flash' has been a very popular choice for gui's and menu's for a long time now.
Skyrim is another AAA-title that relies on some version of Scaleform/Flash.
