Rockstar confirmed over the weekend at the PAX East event that the upcoming release of LA Noire will take at least 25 to 30 hours to complete, and it could take a lot more of you take part in the “unassigned cases,” or side missions, if you will.

The “unassigned cases” (or side missions) are described as additional homicides that help flush out the background story of the secondary characters in the game. While these unassigned cases are not necessary to complete in order to finish the game, they can prove helpful in solving some of the mysteries within the game.

Team Bondi, who is developing LA Noire, says that the game is still on track for a North American release on May 17th and European release on May 20th for both the Xbox 360 and PlayStation 3. While the game has been in development for a long time, the news that it has over 50 hours of dialogue within the game and that it will take 25 or more hours to complete is promising, considering that many games are offering much less gameplay these days.
