Rainbow Six Siege is putting out a call for more operators to play the team based tactical shooter. If you haven't given the game a try, maybe a free weekend will get you interested enough to partake of the sale on the full game later. Of course the timing also coincides with the impending launch of Season 2 for the game next week. The free weekend begins today on PC, Xbox One and PlayStation 4, but each platform will have a slight variation in times:

• Xbox One started first at 3:01 a.m. ET / 12:01 a.m. PT this morning and will continue until 2:59 a.m. ET February 6 / 11:59 p.m. Febriuary 5.
• PC starts today at 1 p.m. ET / 10 a.m. PT and runs through February 5 at 4 p.m. ET / 1 p.m. PT
• PS4 also starts at 1 p.m. ET / 10 a.m. PT, but will end a day later on February 6 at 1 p.m. ET / 10 a.m. PT
