Rainbow Six Siege - Everything we know about Zero

Rainbow Six Siege's new operator Zero could become one of the game's most popular operators, but for some fans, his arrival will be a little bittersweet. People have long requested the opportunity to play as Zero, though this probably isn't quite what they imagined.
Zero is the code name of Sam Fisher, the hero of the Splinter Cell series. The last time we got a Splinter Cell game was back in 2013, and there has been a growing sense of frustration that the series is stagnating. Since then, Fisher has made a few similar spin off appearances, with his arrival in Rainbow Six Siege Operation Shadow Legacy a continuation of that.
On one hand, it proves that Ubisoft has not forgotten about Fisher, and by extension, has not forgotten about Splinter Cell. But on the other, it could be further indication that Ubi is trying to airlift Fisher out of his own franchise, using his popularity as a jumping off point without needing to put the work in to revive Splinter Cell as a whole.
