In my humble opinion, CoD BO1 is the best CoD in the series. I'll explain why. The game has a very strong plot, characters, and an interesting time period - the Cold War. There are no fancy weapons or anything like that here. It is very interesting to shoot from ordinary barrels. Interesting locations: Cuba, Vietnam, Baikonur. The appearance of Reznov from WaW is also encouraging. In technical terms, the game just holds up really well, despite the old engine, it’s very pleasant to shoot, and because of the plot, you don’t really pay attention to the outdated textures. In the story, we play as Alex Mason, who is being interrogated by the FBI to find out what these numbers are. The levels take place in his memories.
