It is four years since you last battled Elexis Sinclaire, a beautiful yet ruthless scientist who will stop at nothing in order to redesign humanity according to her own sick fantasies. It is up to Blade to succeed where the police force has failed and bring Elexis and her multi-billion empire, SiNTEK, to justice. You will be helped along the way by a computer hacker called JC and Jessica Cannon, a talented rookie who has a talent for breaking into secure places.There are many dangerous enemies to face throughout SiN Episode 1: Emergence, including mutants that evolve as you fight them, and jetpack soldiers. Your foes are highly intelligent, adapting to your actions and working effectively on their own or as part of a team. You can outsmart your opponents by using the surroundings to your advantage, such as setting up traps using various elements of the environment.
