Split screen

Does anyone think that it is still possible for split screen in halo 5. What 343 could do is add it in a update. Split screen would only be for forge, customs and non competitive also campaign . 2 players in one console will just drop to 30fps with 720p. 4 players on one console could be 20 fps and 400p.
( Sorry about my grammar and correct if I’m wrong)

343 has already stated that they cannot add splitscreen in the form of an update because it would supposedly just break the game. Note that this is what 343 said, so take it as you will.

In addition to that, a thread dedicated to splitscreen already exists ,and you should post there if you have any more concerns regarding splitscreen.

sadly not possible
