Welcome back, 47. Although we know you've gone into retirement, your elite skills are required once again. The question is -- are you prepared?

Hitman 2: Silent Assassin requires the utmost thoroughness of groundwork, a mastery of weapons and perhaps a bit of luck. You'll need to know when to strike, and when to hide. It's a deadly game of cat and mouse where you must assume the identities of your victims to survive. Question everything and trust no one. Remember, you've got a reputation to protect and a bevy of enemies that are looking to eliminate you before they become targets themselves.

Although we trust you'll have little problem completing your objectives, the following guide has been issued for your reference. Inside, you'll find an outline of the various locales you'll visit throughout the world, a weapons/equipment lexicon and a modest comprehensive walkthrough.

Good luck 47, and watch your back. The enemy is closer than you think.
