The multiplayer seasons are obviously going in order of Halo game stories. So Halo CE is next after reach.
- CE versions of later armours would be interesting
- 343 guilty spark, arbiter head/helmet, CE magnum and energy sword charm and so on
- Like how vehicles can have different tires and such. They could have a CE warthog, wraith, banshee. They could have the CE AR and so on…
- The loading screen could alternate between the current one and concept art from past and current Halo
- I don’t know if it would be a problem to implement these things but for the final idea that I have for now: There could be classic sound effects such as the CE AR sound effect for nostalgia reasons obviously
