If you want to check out an RTS game that uses deception and trickery as a key part of its gameplay, R.U.S.E. may be for you. Today the open beta of the game from developer Eugen Systems and publisher Ubisoft launched today via Steam. Anyone with a Steam account can now download the beta test for the WWII themed game which has six factions (US, USSR, UK, France, Germany and Italy) and seven multiplayer maps which can be played in a variety of modes. There's no word on when the open beta will end.

In related news, Ubisoft has now confirmed June 8 for R.U.S.E's release date in the US. Previously the publisher stated the game would be coming out on June 3.
