Alekhine's Gun

After you complete a level, you are rated on your performance. You are given a ranking based on whether you made any noise, if any bodies were found, if you were spotted, and so on.

To achieve a Ghost ranking, a lot of factors come into play. Ideally, you want you numbers to be:

• Noise: Should be 0 - Noise can be a number of factors; gunfire (both yours and enemies), public assassinations (in view of others) and (strangely) bodies being discovered. Everything you do must be silent and in private (killing targets without being seen). Running and whistling oddly have no effect on this ranking.
• Violence: Should be 0 - As long as you aren’t “violent” in anything you do, meaning you can’t be seen assassinating a target or outright kill any enemy, this will remain zero. If you kill a target, it has to be an accident.
• Accuracy: Should be 100 - This can only be accomplished if you do not use any guns.
• Professionalism: Should be 100 - To keep this score up, only kill your intended target(s) and you must make each one look like an accident.
• Spotted: Should be 0 - When enemies are suspicious of you, an exclamation point will appear at the top of the screen. When a circle completely closes around the exclamation point, you are spotted. If the circle doesn’t close completely and then disappears, you are not fully spotted and are safe (for the time being).
• Alerted: Should be 0 - For every enemy that responds to you being spotted counts as an alert. Lesson here is to not get spotted at all.
• Bodies Found: Should be 0 - For every target you kill, make sure you hide their body.
• Enemies Killed: This number should only be your assassination targets.
• Innocents Killed: Should be 0, no question about it.
• Accidents: This number should be no more than how many targets there are in the level (all assassinated targets must look like accidents to get 100 in Professionalism).
• Close Encounters: Should be 0 - If you silently take someone down with chloroform or garrote, it counts as a close encounter. To get a Ghost ranking, all assassinated targets must look like accidents (to get 100 in Professionalism) and neither of these is an accident weapon.
• Time: (not a factor)
• Difficulty: (not a factor)
• RP Earned: (not a factor)

This can easily be done on Level 1, ‘Ghosts of the Past.’ Refer to “Once Upon a Time” for a video on how to get this and five other achievements in the first level.
