Amazon L.A.Noire Pre-Order Bonuses Improve Your Fighting Skills

Amazon has released their bonuses for pre-ordering L.A. Noire. So if your looking to pre-order L.A. Noire through Amazon, you'll be pleasantly surprised to know that you will receive $15 Amazon credit for future purchases and an in game piece of DLC, The Broderick Detective Suit.
The suit will improve your fist-fighting abilities and increase resilience to damage (In-game only unfortunately) Surely other retailers will include pre-order bonuses and maybe special editions for this game, but Amazon's bonuses seem pretty nice so far. Maybe you can save that $15 for when the next GTA comes out.
