Like in the previous installments of the inFamous series, karma is one of the most important elements of gameplay, influencing the course of certain missions, types of powers wielded by the character, or the way the NPC characters act around him. Delsin can accumulate both good and bad karma, and their current state is always visible in the upper left corner of the screen. You should decide whether you want to be a superhero or a vile criminal at the beginning of the game and stick to it throughout it. This is further emphasized by the fact, that different attractions are intended for a hero and different for a villain, which can be inaccessible to you if you decide to "change the camp" frequently. A taken "karma path" influences the course of some of the missions, and powers acquired by the character - some are only available to the good / bad archetype. It would be advised to complete the game at least two times - especially because there are different trophies prepared for a hero / villain.
The actual karma level is mostly influenced by hey decisions, like the one from the above screenshot (the final part of the prologue). Those decisions can impact the way the story develops and if you will gain access to certain quests.
Karma selections isn't naturally limited only to the "main decisions", because it evaluates a whole number of different activities performed by the character. Generally, you must pay attention in all the areas where there are blue / red icons symbolizing good / bad karma respectively. Rescuing (good karma) or finishing off (bad karma) injured citizens, subduing (good karma) or executing (bad karma) of enemies, which have been stunned or have surrendered (example decision can be seen on the above screenshot).
The next component of the game connected with karma are the minor sidequests, which were mentioned in the "Step 5" section. Each one of those tasks are connected with good or bad karma, which means that you shouldn't be doing all of them. Focus on doing those random encounters (even doing them more than once), which are consistent with your "karma path".
Typical, good-karma quests are:
- Encountering a group of drug dealers - take out the armed dealers and destroy the drugs.
- Finding the people held in cages - get close to the cage and release the innocent civilians.
Typical, bad-karma quests are:
- Encountering a group of bio-terrorism protestants - you have to kill them all.
- Encountering a person playing a guitar or standing behind a sign - you have to kill such an innocent person.
