@vaporeon_ the call of duty series has had a survival mode called “zombies” fur a long time now, where you try to survive as long as you can against infinite* waves of zombies. as the mode got more popular over time, increasingly esoteric narratives and secret quests have been added to game maps, which fur a certain kind of hardcore fanbase have long become the “actual” point of the game
* the games always crash due to memory leaks lol, so they always “end” eventually in some way or another
