Ubisoft will throw open the Assassin’s Creed: Revelations multiplayer beta to all PSN account holders tomorrow – but you need to get in quick.

Previously exclusive to PSN Plus subscribers and lucky Uplay participants, the beta will be available to all between September 8 and 11.

That doesn’t mean you can just mosey in whenever you feel like it, though – only a limited number of client downloads will be allowed, meaning if you don’t move fast enough you could still be left out.

Ubisoft has been gradually releasing more features to the beta; you can see details of available content here.

Assassin’s Creed: Revelations launches on PlayStation 3 and Xbox 360 on November 15, with a PC version to follow. It closes the trilogy of Assassin’s Creed II.
