Ubisoft will release a playable demo for R.U.S.E. on Wednesday, reports Big Download after noticing online advertisements to that effect. The World War II real-time strategy game has already had an open beta and a free weekend on Steam, but there is no word on what the new playable demo will include, though presumably one thing it will not include is Ubisoft's intrusive DRM, which they recently announced would not be included in R.U.S.E.
