Tom Clancy's Rainbow Six Siege is an online tactical shooter video game developed
By Ubisoft Montreal and published by Ubisoft. It was released worldwide for Microsoft
Windows, PlayStation 4, and Xbox One on December 1, 2015; the game was also released
for PlayStation 5 and Xbox Series X/S exactly five years later on December 1, 2020. The
game puts heavy emphasis on environmental destruction and cooperation between
players. Each player assumes control of an attacker or a defender in different gameplay
modes such as rescuing a hostage, defusing a bomb, and taking control of an objective
within a room. The title has no campaign but features a series of short, offline missions
called, "situations" that can be played solo. These missions have a loose narrative,
focusing on recruits going through training to prepare them for future encounters with the
"White Masks", a terrorist group that threatens the safety of the world.

Ubisoft announced the Summer season for the UK Ireland Nationals (UKIN). The prize for
the winning team will secure a place in the 2021 Challenger League and a chance to
qualify for the 2022 European League. The group stage of the league will start on 29th June
2021 and run until 27th July 2021 on Tuesday and Thursday evenings, for a total of seven
playdays. The top two teams will automatically qualify for the UKIN finals weekend on
28th and 29th August. The third and sixth placed teams will participate in a best-of-three
playoffs that will take place on 29th July and the two victorious teams will also participate in
the finals weekend.

Ubisoft revealed an extensive partnership with award-winning songwriter and producer The
Toxic Avenger, for the composition of original music for the Tom Clancy’s Rainbow
Six European League. Building upon the Rainbow Six Siege Main Theme, the European
League new music will enrich the playday streams and offer viewers original music to enjoy
