We're seeing a lot of great trailers this season, lots of running around and explosions as is typical of this time of year. Tis the season to be murderous. Traditionally, Ubisoft don't much get into the spirit of the season but today they've taken the cake with a Rainbow Six Siege trailer, above, which evokes scenes from real sieges and movies in an unashamed montage of violence.

Rainbow Six Siege is due out December 1 and is currently £49.99 on Steam.
