This weekend marks the first Rainbow Six Siege referral free weekend, where players who own the game can invite their friends to try it for free. Each player will receive 4 invites that they can send out via email. Once your friends have them they can proceed to download the game in full and have access to all of it's features and game modes until December 20th at 9:00pm PST. The weekend officially begins today at 3:01pm.

As an added bonus for getting all of your invites out the door, game owners will receive a 24hr XP boost for every invitation that gets activated this weekend. Invitees will also get a deal out of it, in the form of a 25% discount on the game if they want to keep playing it after the free weekend ends.

Rainbow Six Siege has been getting great reviews for it's tactical team focused multiplayer, which is a refreshing change from the glitchy shooters that currently dominate the FPS market.
