Use the following trick if you are finding it difficult to unlock all of your 
powers from missions only. After you have built up your character enough to be 
somewhat dominant (see recommended skill set below), go into an area where you 
have not restored electricity to yet. Once there, you can grab the attention of 
multiple enemies by zapping them. Get the attention of as many enemies as 
possible, and they will all chase after you. Lure them into an alleyway that is 
narrow, then kill them. Use any powers that you have unlocked up to this point 
to ensure your survival. You may find other battle tactics to be more useful 
which you can develop and use for yourself, but the battle tactic that is listed 
here is recommended. Note: Once you lure a large group of enemies into an 
alleyway, throw lightning grenades/bombs at them and use lightning strikes to 
burn them. Throw the grenades/bombs at enemies that are bunched up together in 
order to get multiple kills at the same time. The more enemies that you kill at 
the same time, the more experience you will get. Once all enemies are dead, if 
there are any wounded enemies that are still alive but are struggling on the 
ground, use the Life Leech skill (R1 + Square) to suck the neural electricity 
out of them. This will restore all of your electricity/energy power so that you 
can repeat the same tactic. Be careful; when using this strategy watch out for 
turrets mounted on trucks. They are usually located at intersections and up on 
the railways. A good way of destroying them is to zap the front of the truck, 
where the engine is located. The entire truck will explode, and it will usually 
take out the turret as well. It is recommended for you to be pursuing an evil 
karma state, as the Life Leech will give you bad karma. It is recommended you 
build up these skills as much as possible before trying this tactic.

  Life Leech 
  Lightning Grenades/Bombs 
  Lightning Push to deflect rockets or push enemies away from being too close 
  (not required but recommended) 

  Lightning Strike 
  Sniper (can be useful if you would rather just snipe the enemy behind the 
  turret) 
Try upgrading all of the skills that reduce damage taken by Cole. Also, upgrade 
the increased electricity absorption rate skill.
Car catapult 
Stand on the end of a trunk of a car. It must be a long trunk. Use the thunder 
attack. It will blow the car up and send you flying high up.
