Ubisoft announces Rainbow Six: Siege, a new installment in the tactical shooter series in the works for release next year on Windows, Xbox One, and PlayStation 4. This E3 trailer from the game says it's pre-alpha gameplay footage from a multiplayer match, and here's the announcement:

Today, Ubisoft announced the development of Tom Clancy’s Rainbow Six Siege, the latest in the best-selling Tom Clancy’s Rainbow Six franchise. Tom Clancy’s Rainbow Six Siege will be available in 2015 on PlayStation®4 computer entertainment system, Xbox One, the all-in-one games and entertainment system from Microsoft and Windows PC.

Development of Tom Clancy’s Rainbow Six Siege is being led by Ubisoft Montreal. Inspired by real world counter-terrorist organizations, Tom Clancy’s Rainbow Six Siege puts players in the middle of lethal close-quarters confrontations. For the first time in a Tom Clancy’s Rainbow Six game, players will engage in sieges, a new style of assault where enemies have the means to transform their environments into modern strongholds while Rainbow Six teams lead the assault to breach the enemy’s position. Tom Clancy’s Rainbow Six Siege gives players unprecedented control over their ability to fortify their position -- by reinforcing walls and floors, using barbed wire, deployable shields and mines, and more -- or breach the enemies’ using observation drones, sheet charges, rappelling, and more. The fast pace, lethality and uniqueness of each siege sets a new bar for intense firefights, strategic gameplay and competitive gaming.

Tom Clancy’s Rainbow Six Siege also features a technological breakthrough that redefines the way players interact with a game environment. Leveraging Ubisoft Montreal’s proprietary Realblast engine, Tom Clancy’s Rainbow Six Siege incorporates procedural destruction that is realistic and unscripted, meaning the environment reacts authentically, distinctively and dynamically, based on variables like the caliber of bullets or the amount of explosives used. This advance allows players to leverage destruction in meaningful ways. Walls can be shattered, opening new lines of fire. Ceilings and floors can be breached to create new access points. This ability to modify the level design in real time enables players to create new gameplay opportunities directly within the game level.

“As fans of Tom Clancy’s Rainbow Six and tactical shooters in general, we set out to create the game we always wanted to play within the counter-terrorism universe. We asked ourselves ‘how could we capture the incredible tension and unique tactics of these confrontations?’ We found the answer in the Siege gameplay and procedural destruction.” said Xavier Marquis, creative director at Ubisoft. “Tom Clancy’s Rainbow Six Siege is the game that Tom Clancy’s Rainbow Six fans have been waiting for, and first-person shooter players will be drawn to its unique gameplay.“
