Recruit civilian
When in multi player mode, go up to a civilian and press [R] + [White] to make that person a member of your gang.

Recover from burning
When on fire, enable any weapon code to get up.

Recover from knockdown with weapon
Whenever you are knocked down by enemies, enable a weapon code. You will be back on the ground standing, with a weapon to throw.

Destroying buildings
Use any and all explosives to your advantage. Rocket launchers, grenade launchers, and even molotov cocktails can be used to blow up buildings. When throwing an item into a building, face a window directly and it will go right in. Destroying buildings is where the big money is at.

Easy power-ups
Find an area in any level where you can run back and forth reasonably far and has weapons power-ups on either side. Draw a large crowd of enemies between this area and simply proceed to run back and forth. When you are ready to let loose, turn around and begin to strafe. Run to the other side as you pick up all the diseased ones' health and time bonuses. When you reach the other side, take your new weapon and start again.

Recommended weapons
Although the AK47 has more power than the M-16, it has a slower rate of fire and not as much range. The mini-gun can carve through a crowd full of people in five seconds or less.
