Why call of duty is failing(I will tell you why)

 WARNING: this post will be long, And i mean long. Call of duty Is a famous franchise created by Activison and Infinity ward. With Its new release Call of duty Black Ops Cold War. The game is dying rapidly, mostly zombies. with the apparent cod zombies chronicles 2. The game in my opinion will rise, but not too much, as leakers have found that Tranzit, die rise, and die reise are returning, It started from a game that became so popular, to a game that is dying rapidly, what happend, I will tell you why, First off we have to start at the beginning, Call of duty 1 was a simple but interesting game, since It was just a first person shooter, there was really nothing special about the game, It was just simple. It started to gain popularity around WAW, a video game that had no popularity around its multiplayer. More about zombies, the maps were just simple a small map, known as nacht der untoten. Until pack 1, which introduced perks, which gained call of duty more popular, around zombies, the perks were: juggernog speed cola quick revive, stamin'up. And double tap, these perks would become more iconic as the series grows, then a couple of years later, the famous Call of duty Black Ops 1 came out, more about the zombies same as WAW, but the maps were more designed, and more cared about, the maps were known as, FIVE, KINO, SHI NO NUMA, and much more, then 2 years later bo2 came out, which became the most popular game, because of Nuketown, which bo1 had, Around bo4 was the decline of Black ops, bo4 took on the battle royale, tradition, like fortnite and pubg, more of a copy of pubg, the zombie maps were bad, more bader then bo1. Black ops cold war, was the death of zombies, as of right now less and less players are playing Black Ops Cold War. And the decline is getting worse since double tap is not returning. Instead it is death perception, Now lets talk about the theory, the theory is that Black ops and call of duty, is getting boring since its the same stuff just updated graphics. And that is my reason for call of duty is failing, Good bye and have a nice day.
