Almost an entire decade has passed since the launch of Rainbow Six Siege, which means it is now a far cry from the game it once was. Those who started Rainbow Six Siege in the first year of its launch and have, either consistently or sporadically, remained faithful to the game over the years likely know just how differently it plays now compared to how it used to play. However, that is all about to change when Rainbow Six Siege X launches in June, as it aims to usher in a brand-new era for one of the best tactical shooters out there.
