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. Note: This was found in the demo. It may not appear in the full version of the game.
Damaging enemies
When being chased by a large group of enemies or when there are many enemies nearby, get to the top of a building. Fire some bolts down. They will usually crowd to the closest possible spot to you. Time you jump correctly and drop into the middle of them holding Square. Most of them should die.
Defeating Kessler
While this boss may seem easy on the easier difficulties, in Hard mode this battle can prove quite difficult. The following are a few quick hints as to staying safe and taking off the most damage. First off, keep moving. Standing in place makes you an easy target for mines and earthquake, and you will often get chances to regain energy from the wires. Second, keep your shield up. This will keep you safe from ray attacks and will allow you to concentrate when damage can be done. Also, use your dodge roll to ensure you do not take damage from his blast. If the blast hits you, he will most likely quake immediately after and very close to you. This will only add insult to injury and leave you at near death. If you find you will be caught by a quake, try to run out of the arena. You will be snatched and thrown and suffer no damage from the quake or fall. Later in the fight when Kessler quakes and his echoes appear, try not to worry about them. If you continue to move as advised, they will disappear before getting near. As for his robots, constant moving will keep their grenades at a safe distance and they can be picked off with ease and precision. The best way to damage Kessler is to use your fully upgraded grenades in between his ray attacks. After he completes one shot, drop your shield and throw one in the area he spawns. Note: His spawn points may be a few feet away from his previous spot if you are standing still in this phase. After one is thrown, quickly raise your shield and repeat. Grenades take off large chunks of health and will put him down rather quickly.
Defeating Ulden
Use the following trick to defeat Ulden without taking damage (when the bridge is gone). Go to the back left-hand side and hang from the ledge. You can defeat him without taking damage.
Easy "AC/DC" trophy
Before you re-establish a circuit at a substation, press L2 to absorb electricity from it. Because it does not run out you will eventually unlock the trophy. To do this easier, while L2 is held, hold PlayStation Logo and turn off the controller. Cole will continue draining electricity while the controller off. Once you stop draining power the trophy should become unlocked.
Easy "Good..." and "Evil..." trophies
Play through a mission and finish it using actions to unlock either a "Good..." or "Evil..." trophy. Immediately after the mission success message appears, pause game play and choose to abandon the mission. Although you have to repeat that mission, the trophy that you earned will still be recorded. When the mission is replayed, use the opposite actions done in your first attempt to unlock the other trophy. By doing this, you will not have to repeat the enter game twice as good and evil.
Easy experience points
Find a Dustmen Conduit in The Warren. They frequently spawn three small scorpion-like creatures that are easily killed. Find a safe location (for example, the top of a roof) where the Conduit cannot shoot you with his rocket launcher and the spawned creatures cannot reach you. Keep attacking the spawned creatures for easy experience.
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)
Note: Try upgrading all of the skills that reduce damage taken by Cole. Also, upgrade the increased electricity absorption rate skill.

Easy Good or Evil advancement
Find the sick citizens on the ground. Heal them to increase your Karma by three points or drain them to decrease it by three points.
Get maximum shards without finding any of them
Note: This was done with the evil side. Kill someone in yellow you will be rewarded with shards. After getting killed, you can receive shards again. By doing this you get maximum shards without trying. Note: The trophies for finding shards cannot be unlocked through this method.
Recover energy
Use your lightning bolt (which does not cost energy) to charge light post, battery, or another object that can be drained of energy. Drain it after it is charged. If the object does not explode, your entire energy meter will be filled.
Shock a pedestrian, then walk up to them. Lock on, then repeatedly press Square repeatedly to restore your power.
After killing a person, shock their body with your basic lightning bolts that require no energy. Press L2 while they are sparking to absorb the energy and recharge.

Sly Cooper reference
Move the camera in for a close-up on Cole's backpack to see the Sly Cooper logo in the lower-right corner, just below the "3".
Sly Cooper References
In the game there are 2 known references of the company developer, Sucker Punch's, previous game series, Sly Cooper.
1. When looking at Cole's back pack, look near the bottom, you should see the blue and white raccoon logo from the Sly Cooper games.
2. On one of the buildings in the city, there is a small marquys listing a few movies. The 1st movie on the list is "Sly Cooper 4"
There may be a reason why these little easter eggs are there. Almost a year ago, Sucker Punch announced the develpoment of Sly Cooper 4 for PlayStation 3. But since then there has been no evidence of anything of the game besides the announcement. Sucker Punch probably changed thier minds and decided to make ths game, inFAMOUS. What this could lead up to is the true development of Sly Cooper 4.
Note: These references were found in the American PlayStation inFAMOUS Demo from the Online PlayStation Network Store. Results may vary if searching in full game of inFAMOUS.
