After a long hiatus, which intersected with the canceled Patriots game, Tom Clancy’s Rainbow Six returned to market with Rainbow Six: Siege in 2015. The online tactical shooter launched to positive critical reception but little fanfare, its early days beset by game-breaking bugs and frustrating server errors. Ubisoft Montréal navigated the maelstrom of issues over time, elevating the title to a standard of quality where it could competently dominate in the oversaturated games-as-a-service space. With Siege’s PvP multiplayer on lock, Ubisoft tried its hand at PvE by building upon the alien-infested Outbreak mode that debuted in Siege. The publisher originally subtitled the endeavor Quarantine, then rebranded as Extraction because of the coronavirus pandemic. Regardless of its naming conventions, many would argue the PvE experience hardly stood a chance.
