Sucker Punch is focused on making us as players feel powerful in Infamous 2. There are 50 powers for Cole to tinker with, and after playing for a bit, I can already tell I'm going to be experimenting like mad.
The Kinetic Pulse allowed me to levitate a car and then fire it off like a bullet -- I could even stand on the car, lift it, and fire it out from underneath Cole's feet. The Bolt Stream allows Cole to spray out mini-blasts of electricity like a machine gun, the Ionic Drain sucks the lifeforce from the bad guys around Cole, and the Firebird Strike has Cole fly for a brief second before exploding out in a burst of electricity.
The coolest power addition, though, isn't even a power; it's the quick-switch option. At any time in the game, I could hold left on the d-pad and assign the unlocked abilities to a button on the fly. I could try the napalm grenades, get sick of them, and easily assign an electrocution grenade without having to jump through menu hoops.
