|A Genocide Man tracks and kills populations of genetically modified humans.|
Here is a link to Genocide Man, an awesome web comic by Remus Shepherd.
I've never been that into web comics, none have sparked my interest up to this point. Genocide Man, however, is really good. I'm only through a couple of chapters right now but the story is great, the art is perfect for the story being told and the world building is fantastic.
It's a perfect read for scifi fans, fans of web comics and especially fans of post apocalyptic settings. It's no clearly post apocalypse, it's more of a slow downfall.
