Rainbow Six: Vegas 2 Easter Egg - Hidden Text in Communications.

In-game, sometimes your field-operator, "Six", or a member of your team calls you, that appears in the upper-right of the screen.
On the left side of the radio-communication, is written:
"Même en mettant je jeu sur pause il est impossible de lire ça.".
That means:
"Even if you pause the game you can't read that text.".
