You are John Blade, commander of HardCorps, an elite security force dedicated to protecting the people of Freeport City. Four years have passed since your first battle with Elexis Sinclaire, a beautiful, brilliant, and ruthless scientist who is out to remake humanity according to her own twisted vision. The law has failed to bring Elexis and her multi-billion dollar empire, SiNTEK, to justice, so Blade is determined to take matters into his own hands. Joining Blade on his mission are JC - a hacker with a secret to keep - and Jessica Cannon, a fiery rookie who can find her way into any secure facility.
Good but short, the ambience, the backstory and almost everything made me remind Deux Ex, in some manner Sin is a couple of years before Deux Ex talking of the thechnological development, a couple of years before augment implants appear... or maybe in other part of the word.
