If you were selected to take part in a beta on PC or redeemed a guaranteed access code, the beta should appear in the Uplay client inside the Games
tab. The beta will be added to your Ubisoft account shortly before it starts. You should also receive an email confirmation when it is ready. If you cannot find the game there, show your hidden games in Uplay
to check if it is among them.
If you were invited by a friend to join the beta, please also double check if the invitation went through. You may need to access the beta website first.
