Didn't find this posted over here, so I thought I'll share some tips and a few tricks
Tip 1: How to get a police pistol and escape without getting shot to death
Step 1: Find a cop on his own patrolling on foot and make sure there's no other cops in the vicinity
Step 2: Provoke him by beating him up so he gets his gun out
Step 3: Disarm him and quickly holster the pistol by pressing down on the D-Pad
Step 3: Flee by vehicle (recommended) or foot if you can
Step 4: Go to your nearest safehouse and make sure the pistol is holstered and then save your game any way
Step 5: Load the save and you'll still have the pistol on you
With this tip as soon as you disarm the cop and take his pistol and then quickly holster it, the cops won't shoot you and the heat won't increase and therefore you can get away with a gun in 1 piece.
Tip 2: How to obtain the Enter The Dragon martial arts outfit "Hong Po"
Step 1: Get a few buffs ie combat, health regen
Step 2: Go to a martial arts school it should be like a fight club (not the combat training)
Step 3: Survive all 6 rounds making sure on the last round you get max face
Step 4: Go to your nearest safehouse and the outfit should be in presets.
Hope this helped and I will be posting some more useful tips and tricks soon.
The Hong Po outfit tip you gave is not working at all. Could you clarify please? I'm getting a feeling that this isn't true.
