Assassin's Creed Chronicles: Russia

Every time you pass a checkpoint in AC Chronicles: Russia, you will be assigned one of three ratings: Shadow, Assassin, or Silencer, depending on your play style.

To achieve a Shadow Gold rating, you must be entirely stealthy, and not kill or take down a single enemy.

Many of Anastasia's sections will yield Shadow Gold, especially in Sequence 3, where she doesn't have Helix ability. Enemies will be very sparse. As long as you are careful, you are likely to obtain this naturally over your two playthroughs.
