Ubisoft is holding another Rainbow Six Siege free weekend this month, giving gamers who haven't yet sampled its terror-busting pleasures (or who just prefer to play when it doesn't cost anything) a chance to dive in and shoot some bad guys.   

The free weekend begins on February 15 (so not this weekend, but next) and runs until February 18, and will include access to the full game, including all maps, modes, and Operators. As always, progress will carry over if you opt to purchase the full game once the weekend is complete.
