If you're wondering whether Rainbow Six Siege could ever possibly live up to the hype behind it, you might be interested to hear that there is a free trial period coming in the near future. To be more specific, you'll be able to play around with all of the Operators, maps and game modes from August 16-20.
Rainbow Six Siege might not be my cup of tea, but it's still a pretty darn enjoyable game, and one that Ubisoft has done an excellent job of supporting throughout the years. So if you're up for a heavily team-based shooter and you don't mind the somewhat steep learning curve, I would highly recommend you give it a chance. After all, it's entirely free for a few days!
You can learn more about Rainbow Six Siege, as well as grab the game itself once the free weekend goes live, over at the official website. And as a final note, here's one of the earlier gameplay videos to hopefully give you an idea of what to expect. Enjoy!
