Ubisoft has a ton of sick-ass looking games coming out but I really wish that they would lose the bull-shit gamer voices in the walk-through. They all sound like dip-shits and are coming off way to hard to be "in to the game". "Roger that"--fuck you. Chuckle heads aside this could be a very interesting title if you like playing with others and shooting shit.
Rainbow Six Siege is set for a releases on Xbox One, PS4 and PC in 2015. RB Siege is described as a co-op multiplayer-focused game in which enemies have the means to transform their environments into strongholds, while Rainbow Six teams led assaults to breach them.
Honestly I don't see this coming out to at least 2016 but if the end product can deliver and on time than Rainbow Six Siege could very well be purchase worthy.
Peep the trailer and read some of the info from the game's official site.
