It will unlock A New York Minute if you complete one of the New York minute levels, but upon loading it up you get A Few Hundred Bullets Back, An Echo Of The Past, You Sure Know How To Pick A Place, A License To Kill, and All Of The Above. I believe if you get one head-shot, melee, one kill in shoot dodge, and shoot one airborne grenade you will get With Practiced Bravado, You Play, You Pay, You Bastard, One Bullet At A Time, and You Might Hurt Someone With That; but i have not tested those.
