Meet the world's most accomplished and wealthy assassin, forced back into action by treason. He is well-known as a hired killer but he still has a sense of loyalty and justice. And a past that catches up with him - he is plagued by deception and genetic butchery.

Here the outcome of your actions and your proficiency are measured on a balance between stealth and aggression. As the enigmatic Killer, you must use stealth and tactical problem solving to enter, execute and exit your assignment with minimum attention and maximum effectiveness.

Stalk and eliminate your targets using a diverse arsenal of equipment. Plan each assignment carefully to account for multiple paths to completion. Sharpen your skills. Trust no one. Remember: rash decisions bleed consequences. Those will determine if you retire as a millionaire or get permanently retired.

You're in full control and the world will react to whatever you do. Know when to strike instantly, know when to take your time. Use stealth techniques, improvisation and all your creativity to take down your targets in spectacular and ingenious ways. It's too late to back away. Take your chance.
