You’ll just need a referral code
Ubisoft is holding a free weekend event for Rainbow Six Siege on PC. You’ll need to score an access key from a pal (or a friendly stranger) who owns the game, but that shouldn’t be hard.
Current players can send up to four Siege codes, and for each one that gets redeemed, they will earn a 24-hour Renown Boost (but not until “shortly after” this event ends).
Folks who redeem a free-weekend code can pre-load the game immediately and will be able to play from today at 3:01pm Pacific until Sunday, December 20 at 9:01pm Pacific. Siege is also 25 percent off ($45) to own on Uplay. Any progress you make this weekend will transfer.
By all means, unload your extra codes in the comments.
