For those too young to remember, back when Halo was huge every gaming publication was always like “is this new shooter X going to be the Halo killer?” Every time a big multiplayer shooter was announced, there was speculation about whether it was going to be the Halo killer.
Now that Halo is dead, which game was the Halo killer?
I think this is always the case with large IPs. It’s never one game or community that kills them. They’re always their own worst enemy.
