Though it only launched a few weeks ago, Ubisoft has launched a special free-to-play weekend for Rainbow Six Siege that starts today with only a few caveats. First off, the event is only happening on PC and only players with certain referral codes get access.
Every player who currently owns Rainbow Six Siege can get four access codes via the official website, and distribute them out to friends or other players to create their own squad. New players can access the game from today at 6 p.m. EST to Monday December 21 at 12:01 p.m. EST. In addition, anyone can grab the game with a 25% discount this weekend as well.
Rainbow Six Siege is currently available on Xbox One, PS4 and PC.
