InFAMOUS Second Son/The Karma System

This game runs in a morality system, basically meaning the game shapes around whether you have Good or Bad Karma. These will also effect your upgrade path, as there are some powers that are linked to a certain Karma. Therefore, to unlock everything, you must play the game at least twice.

Good Karma
You can gain good Karma by:
 * Choosing "Blue" (Good) choices within the story.
 * Subduing surrendering enemies
 * Healing injured civillians
 * Performing drug busts (subduing the dealers and destroying the drugs)
 * Subduing enemies with Neon (requires an upgrade, listed in the powers section.)
 * Freeing suspected conduits from suspicion pens.
 * Rescuing suspected conduits being assaulted by mobs (second island only)

Bad Karma
You can gain bad Karma by:
 * Choosing "Red" (Bad) choices within the story.
 * Executing surrendering enemies
 * Executing injured civillians
 * Kiling police and civillians
 * Disrupting activist rallies
 * Killing street musicians
 * Killing Akuran gang members
 * Killing DUP troopers
 * Destroying suspicion pens
 * Executing suspected conduits being assaulted by mobs (second island only)
 * Killing enemies with Neon (requires an upgrade, listed in the powers section.)

Outcome
The missions you do and the ending you get will depend on your Karmic Choices. Such choices require you to choose one scenario out of two. A "red" (bad) scenario (to earn bad karma) and a "blue" (good) scenario (to earn good karma). Your ending depends purely on if you have good or bad karma.
