Tom Clancy's Rainbow Six: Siege is an upcoming first person shooter made by Ubisoft. It was announced by Ubisoft at E3 2014. It is considered to be a successor to Tom Clancy's Rainbow 6: Patriots, which flopped and was canceled.
Like all other titles in the series, it will focus heavily on team play and realism. However, there are major differences to older versions of the game, featuring a heavy multiplayer focus and destructible environments. The setting will include hostage type scenarios.
