Hint: Extra power with EMP gun
When you are charging up your EMP gun, wait a few extra moments
until you see a light blue ring appear around the energy ball. It
will keep your opponent disabled a few seconds longer.

Hint: Faster upgrades
Stay by your garage and induce a RIOT by killing the civilians and
other gangs on the street. To get the RIOT factor up faster, blast
away the street cops. When your armor is running low, drop by the
garage and pick up a repair kit. Keep repeating this until you get
enough money for the upgrades. If you "fail" the RIOT, do not
restart by loading the previous save. This allows you keep all the
money, no game penalties will be levied, and you will keep all of
your upgrades. The only thing you will lose are all of your weapons.


Hint: Other towns

following the "M" on the map. You can actually go back to the
previous city at anytime. Pay attention where the exits are for the
