If you’ve been anxiously waiting for the release of the Uncharted 3 Multiplayer Beta to begin you’re in luck. The beta has been green-lit and has begun. You can find the beta content at the US PlayStation Store, where in the new releases you’ll see the content as a PS Plus Exclusive. If you redeemed your welcome back package from the PSN outage, you’re definitely still enjoying the free perks of PlayStation Plus. With one of those perks now being, one of the most anticipated multiplayer betas of the year in Uncharted 3: Drake’s Deception.
Since the beta just began moments ago, you may have some issues getting online immediately, Naughty Dog knows about the problem and is working to correct it. I guess its one of the bad parts about starting up an open multiplayer to tens of millions of rabid fans.
Again: Not able to connect, stuck on "Connecting…" or "Error intializing session mgr" – we're know & getting things back up ASAP
