PlayStation Store Update: L.A. Noire DLC, Assassin's Creed: Brotherhood

Leading the charge today on the PlayStation Network is the Reefer Madness ($4) downloadable content for Rockstar Games' well-received 1940s sleuther L.A. Noire. The new case tasks players with pursuing and bringing to justice a Los Angeles drug dealer who trades in heroin, morphine, and marijuana.

Switching to the PlayStation 3 game download hub, Sony added just one new title today, Ubisoft's Assassin's Creed: Brotherhood ($40). The stealth action game follows the long-knifed Ezio as he once again hunts down the Templars, but this entry has a twist. Instead of fighting alone, Ezio will recruit an army of killers to fight alongside him.

Assassin's Creed: Brotherhood also features a multiplayer component, a first for the popular series. In this game mode, players will receive contracts for the heads of other players. They must sneak around the multiplayer environments and kill their opponents before they fall by the knife to another player.

Gamers hoping to try before they buy this week can grab a demo for Catherine today on Xbox Live. The sampler gives gamers a first look at and feel for Atlus' puzzle adventure game, which is due out in full on July 26.

Living room rockstars can grab new tunes for the Rock Band franchise today. New songs added to the PlayStation Network include two tunes from Christian rock band P.O.D. and one song each from Frankie Goes to Hollywood and Erasure. Songs are available for $2 each.

A full list of the week's deals and new PlayStation Store content, including themes, wallpapers, demos, discounts, and add-on content, is available on the PlayStation Blog.
