Katorga-12, an island like no other. Once a stepping stone for technological development, now an abandoned wasteland. Once a sanctuary untainted by the war which plagued the world. Now a death-trap for all who wish to uncover secrets that are best left buried. What nightmares lie within the abandoned buildings, what horrors hide in the shadows of the former Utopia?

...My name is Alex Mercer. I'm the reason for all of this. They call me a killer, a monster, a terrorist... I'm all of these things. Three weeks ago someone released a lethal virus in Penn Station. I woke up at the morgue. Now I hunt, I kill, I consume, I become. I'm gonna find out who did this to me... And I'm gonna make them pay.
