Hello, I’ve been wanting this since halo 4, and I had read some topics about it, so mi question is, does somebody know If this is coming anytime? Because being able to make survival maps, or fighting courses will be very great and I dont know any news, so if you know anything feel free to say it. Thanks!
As this is a great idea and it has been mentioned many times in the forum, no man, 343i has said nothing about this, sorry 
It won’t happen, maybe in the next game, but I doubt it. Some modders like GameCheat13 (not online modders) have put ai into forge. Also many people have ai maps in Halo CE for PC. (a forgotten gem, there is still a nice little community for it) Actually Halo PC is great for custom maps, the fact that it still has a community after more than 10 without a proper sequel (Halo 2 PC is dead) proves that 343 NEEDS to make us a new pc Halo game. (NOT HALO ONLINE)
hopefully a primitive AI or just a “shell” of an AI would be possible.
One can only hope. My bet is that if we do see it then it will be in Halo 6, adding something that big this late would thoroughly surprise me
