In recent days, the networks are filling with a new Rainbow Six game that Ubisoft would announce at E3 2019. Sources as famous journalist Jason Schreier or analyst Daniel Ahmad (Zhuge EX) claim that the game in question is Rainbow Six: Quarantine, although the proposal of the game is a little less clear.
After several comments and clues pointing to different origins for this project, the general consensus seems to be that Rainbow Six: Quarantine is actually a Rainbow Six: Siege spin-off based on the Outbreak event, a surprisingly crafted three-episode cooperative campaign that we were able to play in March 2018.
Outbreak invited to play as different operators to face zombie-alien invasion. The truth is that we do not know to what extent Rainbow Six: Quarantine is linked to Outbreak, well you could be on your own universe, characters and background. If Quarantine is real, it is most likely that we will see it in motion on June 10 at 22:00 (Spanish mainland time). Check the rest of dates and times of E3 2019.
