Halo 3 Laso issues

So my friends and I have been trying to do the mission “The Ark” for about a week or two. We are unable to complete it due to being randomly disconnected. My guess was the Xbox servers but that would mean they would be finicky for a week or two, which is unlikely. Is anyone else having this problem?

We were also nearing the end of the level where you go and kill the chieftain in the middle of the brute circle

Coop campaign doesn’t use servers, it’s entirely peer to peer. The netcode is pretty unstable, have you tried alternating the host? It seems like whoever is hosting is having a hard time syncing the game state. Also are you on PC or Xbox?

I am on PC. I am usually the host of the game because while I have gigabyte upload and download, I still have input lag whenever either one of my friends host.

That sucks, sorry to hear it. This happened to my brother and me a couple times over the course of our laso playlist completion but luckily for us close to the beginning of the missions and almost exclusively in Halo 2. I’d be quite ticked off if it had happened at the very end of a long mission like the Ark.

We both play on console and had no issues with disconnects while playing through the halo 3 laso campaign. If this problem is persistent, the only thing I would recommend is to try to optimize your runs to get through it as quickly as possible in order to minimize the chances of it crashing. You’ve watched the videos and know the skips and optimal strategies? For example at that last part you mentioned, try to throw a shield drain to the left side of the chieftain so as to take out multiple jet pack brutes quickly. I don’t play on PC so I unfortunately can’t offer any platform-specific advice.

Try having your friend host the next session and see if the stability improves. Input lag will always be a problem unless 343 decides to finally switch it from synchronous to asynchronous. Are the specs of your machines similar? I speculate the wider the gap between them the harder it will be sync the game states.

My Computer has an RTX 2070 Super with a Ryzen 5 5600x and I have 32 Gigs of ram.

And with the whole input delay, my friends don’t even notice it and say it’s fine when I host. But when either one of them hosts, it’s extremely noticeable on my end. And the other friend is fine too. I am clueless on how that makes sense lol

The input delay is a result of the host having to receive the inputs from all players and calculate the new game state then push the update to all players. If you aren’t host the delay is awful. The best way to play coop is split screen, but looks like you are SOL on PC.

Just tried it with another friend hosting, but alas the same thing happened. Disconnected from the sever.

Just beat the mission! Got very lucky. Thanks for all the help!

Hopefully the rest of the game treats you well!

it crashed again at the end of the covenant lol

I’m glad you finally got past it! Best of luck getting through the next few with all the problems you’re experiencing. I guess I got lucky getting through these playing co-op with my brother online, we only had a handful of crashes mainly on Halo2. We play on console though so maybe that made a difference
