The second downloadable add-on pack for crime-embroiled shooter Mafia II will see a September 7 release, publisher 2K Games sent word today. Entitled Jimmy’s Vendetta, the arcade-style outing promises a varied scope of  “more than 30 quests,” which cover assassination plots and explosive vehicle pursuits across the mobster-ridden locale of Empire Bay.

According to 2K, a new built-in online leaderboard system tracks player performance by gauging the brutality of finishing moves. Car stunts, such as lofty jumps and power slides, are also factored into your overall performance score, with added bonus points tacked on for multipliers and combos.

Jimmy’s Vendetta is due out across Xbox 360, PS3, and PC next month for 800 MS Points or $9.99.
