What then will the Afterfall world offer to the player who decides to abandon the main storyline?

A whole galaxy of possibilities. For example, you will be able to join one of the organizations you meet along the way, and perform tasks for them. One of those are Scrappers, a midget-like race living in their fortress made of junk, who are suspicious of any normal human. If you win their trust, however, you will be able to perform contracts for them, giving you access to new parts of the world and unique objects. Another organization the player can join is the great and powerful Trade Federation. It maintains commerce in most regions of the Afterfall world, and gaining its gratitude will give one vast knowledge of farther territories. Additionally, there are numerous gangs and mobs. The Injector Gang, for instance, who illegally manufacture and distribute implants. On top of that there are more than a dozen tribes, a Mutant Liberation Front, religious sects – really, I could go on for a long time; there are so many possibilities the player will never be bored. Some of the organizations I just mentioned are described in more detail on our webpage.
