With closed beta testing of Tom Clancy's Rainbow Six Siege set to begin tomorrow, Ubisoft now offers this trailer to celebrate the occasion. The accompanying description outlines the scope of testing of the tactical shooter: "The Tom Clancy’s Rainbow Six Siege Closed Beta goes live on September 24th. 14 Operators. 3 Maps. 2 Multiplayer Game Modes. Terrorist Hunt. They’re all available for you to experience before Rainbow Six Siege releases on December 1st. We can’t wait for you to join us and your friends in the destructible combat arenas of the Siege." Those interested in participating can still sign up on the official website while Amazon is offering what seems like a sure way to get in, as they are "selling" beta codes for free (thanks GameWatcher). There are even more details in the UbiBlog.
