- In the safehouse living room, there is a table in the back left corner with newspapers titled "The Infinity Ward Times".
- The achievement/trophy "The Pawn" is achieved when completing this mission, as the name signs that the Task Force 141 soldiers were just pawns to assault Makarov's safe house and get the intel that states that Makarov and Shepherd worked together, and killed when no longer needed, and is also a reference to the game of chess, because many players often rely on pawns to do the "dirty work", and are easily dispensable and replaceable.
- In the kitchen, there is a brick cook station with a chimney that goes nowhere as it is under the stair landing.
- The Shadow Company members who throw Roach and Ghost into the pit after General Shepherd kills them are not randomly generated, but the one who douses them with gasoline is.
