Like they have for the past two years with Watch Dogs and The Division, Ubisoft left their last secret for last its E3 presentation this year with Rainbow Six: Siege. After the development limbo that Rainbow Six: Patriots was in, Ubisoft decided to go back to the drawing board and create something more inspired by the tactical roots of the Rainbow Six series. Siege is a multiplayer first game that relies on teamwork and communication in a Counter-Strike styled round-based shooter. Destruction plays a big part, and though the demo above runs on the Anvil Next engine, the small scale of the environment like a two-story house allows the team to create much more dynamic destruction that can give players tactical advantages in a standoff. Rainbow Six: Siege is scheduled to release in 2015 for the Xbox One, PlayStation 4, and PC.
