Ubisoft held a TwitchTV Rainbow Six: Siege unscripted match in which we got to see the PC build of this new tactical game being put to the test by ten players (5v5). In this video, two E3 teams (team Raven Shield versus team Rogue Spear) duke it out. Rainbow Six: Siege looks fun and its destructible environments are the game’s big ace. The game is planned for a 2015 release on PC, Xbox One and PS4. Enjoy!
