Its hard, it's challenging, and it's most importantly nostalgic, because I still remember playing it back in 2015 and it's 2020 right now still playing in Black Ops difficulty (Veteran/Very Hard Difficulty) and omg the death/theme song gives me chills of a 1000 memories comes back. I really recommend this game to those who are beginner to shooters, and wants nostalgia from this game.
