More controversy followed the series this year when it was revealed that Siege would lack any meaningful single-player or campaign component, instead focusing entirely on competitive multiplayer and the esports market. There, Ubisoft debuted Siege, promising a return to the methodical, surgical gameplay of the series' beginnings. Rainbow Six: Patriots made a splashy debut in the press in 2012, but had a surprising flame-out just months later, and the series was more or less dead until last year's E3. The last proper Rainbow Six release was Rainbow Six: Vegas 2 back in early 2008, more than seven years ago. Prior to Rainbow Six Siege, the series that launched the Tom Clancy's brand had kind of fallen off the map.
