The Rockstar Pass – now, still available on the PlayStation Store – is a “ticket”, so to speak, that offers all current DLC, as well as an unreleased piece of content that will arrive next week, for $9.99 total. It’s basically a short-term subscription service for L.A. Noire DLC.
The Rockstar Pass was available when the Store came back a few weeks ago, as was set to only be available until June 14, yesterday’s PSN update.
However Rockstar is extending the time period before this offer expires, until June 21, when the "Nicholson Electroplating" Arson case releases next week on PSN.
The offer is definitely worth it if you’re planning on dropping some dough on the L.A. Noire add-ons, and haven’t already.
