Ubisoft are teasing what appears to be either another beta or a demo for their upcoming title R.U.S.E. Last week, senior producer Mathieu Girard wrote on the game's official forum, "In a matter of days, I will announce a big surprise, a special treat for all our fans."

Now on the game's facebook page is a small image showing the Steam logo and "15-7" (which we assume refers to the 15th of July).

Stay tuned. The game is scheduled for release in September.
