For the longest time, the general release structure for the Halo franchise remained pretty much the same. Every few years, a new Halo game would drop, offering the complete package of a substantial single-player campaign and multiplayer mode. As Bungie grew more ambitious, this Halo release structure would start to gain a few more additions, ranging from the underrated Theater mode to the beloved Forge mode and, eventually, the wave-based Firefight mode. This structure worked flawlessly for years, with even 343 Industries' Halo 4 and Halo 5 following suit. But then, Halo Infinite came along.
