As promised, Ubisoft has launched a free weekend event for Rainbow Six Siege on all platforms. Those on PS4, Xbox One, and PC can try out the full version of the excellent game, albeit with a caveat in the case of the PS4 version.
Siege's free weekend is active now and available to everyone on PC (through both Uplay and Steam) and Xbox One. The latter is true even if you don't have an Xbox Live Gold membership, which is often a requirement to take part in these events. However, if you want to try Siege out on PS4, you'll need to be a PlayStation Plus member to do so.
No matter the platform, you'll have access until February 18. Any progress you make can carry over to the full game, should you decide to purchase it. Siege also happens to be on sale right now, with several editions discounted on the Xbox Store, PlayStation Store, and Steam, which just kicked off its Lunar New Year sale.
After starting out somewhat humbly in 2015, Siege has evolved into one of the best multiplayer shooters on the market right now. Perhaps its biggest update yet, Chimera, is set to launch soon with new Operators and maps, as well as a brand-new, limited-time co-op mode called Outbreak. You won't be able to try out any of that as part of this free play event, though owners of the PC version will be able to test it out ahead of its launch in March as part of a Technical Test Server update debuting next week.
