Ubisoft has released the last gameplay video in its Rainbow Six: Siege series exploring each of the game's counter-terrorism units. This one also happens to coincide with the game going gold ahead of its release in December, meaning the game is finished and off to be printed, pressed and shipped.This latest gameplay trailer focuses upon the Spetsnaz siege operators, showcasing the Russian elite team's various skills and abilities possessed by their members Glaz, Fuze, Kapkan and Tachanka. A personal favourite of mine, Tachanka has a deployable turrey he can use to mow down the enemy and set up a perimeter.Watch the new 'Inside Rainbow' trailer below, then prepare to breach and clear when Rainbow Six: Siege launches for Xbox One, PlayStation 4 and PC on 1st December 2015.
