PC players tempted by Rainbow Six Siege have the opportunity to try the released game for themselves this weekend as it will be free to play.
There is a condition, however. You will need to be invited by an owner of the game, who will get four invite codes from the Rainbow Six Siege website.
That's the best way to experience the game; it relies on cooperation, communication, and teamwork, so best to link up with players you know.
The free weekend is underway and ends on Monday, December 21st at 06:01am CET.
Ubisoft just released the first big patch for the game, so the timing makes sense. If you don't know someone who has it on PC, visit the usual gaming forums and social platforms where the community is likely only going to be too happy to draw new blood into the game.
