Favorite Call of Duty Zombies Map
Der Eisendrache is my favorite map of all time, where it's the closest to perfection a map has gotten. From overpowered and easy-to-obtain wonder weapons, to a fun and engaging easter egg. You aren't forced to do any part of the easter egg to play, aside from the Bows which are essential for survival. The aesthetic, lighting, ambience, and audio quotes have made this map my most returned to over the years.
Revelations is a compilation of old maps from across different COD Zombies games. This map would be at the top of my list if it weren't for the underwhelming ending which wasn't really the end, and hoping that it would be completely unique. The selection of wonder weapons are re-used from previous maps, along with the specialist weapon. Despite this, it is beautiful and the music is still amazing to me.
This map was one of the first maps on Black Ops 4, but also one of the first maps in the Chaos Storyline, which was new to BO4. This map is similar to a "filler" map, where it's small and able to be played without doing the easter egg. IX has trials a player can do for easy and good rewards, helping aid newcomers into the game. While initially hesitant to play or enjoy this map due to the new confusing timeline, I eventually came to enjoy it, consistently using it to level up and for the characters.
