UbiBlog announces that a free weekend for Rainbow Six Siege will begin on Thursday, offering the chance to play the tactical shooter for free for a few days. Here's word on how to access the Windows edition:

More than a year after its release, Rainbow Six Siege is going stronger than ever, with a continually growing player base, high-profile tournaments, and a second year’s worth of DLC releases on the horizon. If you’d like to discover the speed, strategy, and tension of Rainbow Six Siege’s high-stakes counterterrorism matches for yourself, you can jump in for free on all platforms from February 2-5. The free version of Rainbow Six Siege offers access to all of the maps, modes, and Operators present in the full version, giving you the full Siege experience over the free weekend. And if you want to keep playing after February 5, you can grab the full version at a 50% discount for a limited time, and keep all the progress you made during the trial period. The fun starts February 2 on Xbox One, PlayStation 4, and PC (via Uplay and Steam), so gear up and get ready to breach.
