What a lie. The co-op netcode is insanely bad and everyone knows it. Came back nearly 2 years later hoping this would have been fixed by now but nope. Crazy too, Halo’s co-op used to be iconic! I tried convincing my friend to get into Halo and she’s refunded the game now lol.

It’s pretty bad and to be fair it’s exactly as it was on 360. If the both of you are console players, and hang out regularly split-screen is the best coop experience. Anything else and you are SOL.
