10. Corvo Attano
The latest addition to these ranks of assassins, Corvo is the playable character in Arkane Studios' Dishonored. He wields what might be the coolest set of skills on this list too, including but not limited to the ability - teleport short distance, possess animals & humans, slow & stop time and turn dead bodies to ash. The combination of those incredibly effective powers and that bad ass steam punk look means he had to be included on the list.
9. Assassin
From one of the newest to one of the oldest. Assassin was a Commodore Amiga game that came out 20 years ago and starred a character known as, you guessed it, Assassin. Assassin is a side scrolling platform & shoot 'em up in the style of Contra. The original edition featured one of the most unlikely of assassination weapons - a boomerang! The Special Edition, bizarrely, made the change to replace the boomerang with a laser gun. Either way, the protagonist paved the way for many that came after him.
