Infamous (Special Edition) Cheats (PS3)

After you get Thunderstorm you have to protect three 

separate electrical boxes to restore power. Use 

Thunderstorm to do so, then die, walk away from a box 

your protecting or restart the mission all togeather to 

keep all the XP you have earned. If you're using 

Thunderstorm you can kill everyone very quickly and rack 

up a good deal of XP quickly.

Although there are tons of energy sources for you to drain in most cases, you sometimes
get caught in a tough spot trying to survive at a location where there's no more energy to
drain.  

  Use your lightning bolt (costs no ENG) to charge a battery, light post, or other
drained energy source, then drain it once it is charged. If the object doesn't overload
and explode like Zeke's batteries, you will be able to recuperate your entire energy meter
and have a good place to use your precision shot to take out enemies.

Instead of going through the game twice as good and evil to get all of the main mission
trophies (like the Trophies for "Good Eats" and "Evil Eats"), do the mission and finish it
but the second after the mission success box pops up, pause the game and abandon the
mission.  You'll forfeit the mission and have to do it over, but you'll still get the
Trophy that goes along with it. Now, just redo the mission and play it the opposite manner
that you did before (good or evil). You'll get that Trophy, too.
