'The Naked City' Vice Case & Badge Pursuit Challenge

(Available via Game in the UK and GameStop in Canada & USA)

'The Naked City' Vice Case

In this bonus case from L.A. Noire's Vice Desk, detective Cole Phelps investigates the supposed suicide of a stunning fashion model. Can you help Cole unravel the truth in a city blighted by drugs, corruption and greed, where the death of a beautiful woman is never as straightforward as it seems?

The Badge Pursuit Challenge

Hidden around L.A. Noire's beautiful recreation of 1947 Los Angeles are 20 police badges to find and collect. If you can find all 20 of these badges, the dapper Button Man suit will be unlocked which provides extra ammo for all weapons. Each badge also provides 5 additional XP which will help further unlock Intuition Points - special credits that can be used to give Phelps a key investigative insight when you need it most.

'The Broderick' Detective Suit

This unlockable detective suit boosts your fist-fighting capabilities and resilience to damage. Throughout L.A. Noire while working cases, you'll encounter quite a few suspects and persons of interest who prove to be resistant to arrest. Your hand-to-hand fighting skills will be called into action on these cases - the Broderick suit with its enhanced fighting abilities may be that edge in helping make that collar.
