The leaked bit of L.A. Noire downloadable content has been made official, and given a release date to boot. Rockstar has opened a redemption page for the Best Buy launch promotion, which is currently just a placeholder, but confirms the DLC name and launch date.

It's titled the "Nicholson Electroplating" Arson Case, and will come out on June 21. The publisher hasn't announced a price for the DLC, but if you were one of the first 16 people to buy the game at one of the Best Buy midnight launches, you can get it for free. If you do have a code, you can't enter it into the page until the DLC launches next month.

We don't know yet how well the game is selling, but it at least gave the stock market enough confidence to give Take-Two shares a boost. We'll have our own review up soon, but in the meantime you can check out Xav's early impressions, based on his first few hours with the game.
