The story line: Agent 47 finds himself in the midst of a war between two rival contract agencies. When assassins from his contract agency, the ICA, are systematically eliminated in a series of hits, it seems a larger, more powerful agency has entered the fray. Suddenly, Agent 47 loses contact with the ICA. Sensing that he may be the next target, he travels to America where he attempts to carry on with business as usual.

The question of how to get good money and how to use is tricky. But the answer is simple, the cleaner the 'hit' the more money that can be used on reducing your notoriety, weapon customization, specialist equipment and information. Of-course the weapon customization is the most vital part where you can modify the weapon in a variety of ways including sound, recoil, rate of fire, damage, reload speed, accuracy and zoom. Hitman has been sound of its silent techniques, so in addition of that new game play techniques have been added including distraction, accidents, body disposal, human shield, decoy weapons etc. and as per some of the flaws in the previous versions that have been removed as now our Agent 47 can now climb, hide, scale ledges and automatically clear low obstacles. But as these aspects have been introduced to our Agent some more have been added to the AI; the guards will follow blood trails, investigate suspicious items and behaviors. New pathfinder engine provides improved tracking and movement with realistic enemy behavior and interaction.
