Myself and many others were very grateful of 343 releasing the mod tools for Halo 2/3 and I have spent so many hours building maps and custom scenarios. With Infinite being open world, I think having mod support would be amazing for replayability.
I really hope 343 can answer this question sometime, many of us would absolutely love to mod this game with vehicles, weapons, scenarios, etc.
I’d like to know the answer to this too. At the very least fan support for mods is already happening.

(The youtube channel is Gamecheat13’s Alpha Archive series. It does contain very mild spoilers for Halo: Infinite and currently focuses on files in the beta.)
I’m also worried about if we will be getting gametype scripting like what is in Halo: Reach. It allows for the creation of new multiplayer gametypes in MCC’s Reach, Halo 4, and Halo 2 Anniversary. Having that on top of something like Halo 5’s forge system would be incredible.
I could see mod tools coming with Forge or even Forge being advanced enough to make scenarios and such.
I just hope we can mod the campaign
