It started yesterday, but you still have until the 19th of August to jump into Tom Clancy's Rainbow Six Siege, for free. And this is across PC, Xbox One and PlyaStation 4.

Via Uplay, of course. (*Hides*).

But seriously, with 35 million concurrent players and a bustling esports scene, this Rainbow Six is one of the best competitive versions of the game ever released. And you can jump in on all three platforms for the next few days for free.

Players who try the game during the free weekend can carry over their progress and continue to play uninterrupted if they purchase the game. They will also benefit from a discount of up to 60% off on the Standard, Advanced, Gold, and Complete Editions between August 16 and August 27, depending on the platforms.

The full details and timing of the free weekend and the discount are available via the following link: http://rainbow6.com/freeweekend.

The upcoming Operation Grim Sky will feature two new operators, one American Attacker and one Defender hailing from Great Britain, and the first ever fully reworked map, Hereford Base. The full reveal of the Year 3 Season 3 content for Tom Clancy’s Rainbow Six Siege will be made on August 19 during the Six Major Paris.

If you haven't jumped in yet, here's our in-depth review to help you make that jump.
