Crash on Halo 2 Uprising Legendary Co'op

On the MCC on Steam, playing Uprising with a friend on Legendary causes a crash when you get to the halfway cutscene. A friend and I played the mission 3 separate times, all 3 times the game crashed after the first second of the cutscene starting. We have tried swapping who hosts, and did all of the steps to repair the game for the last attempt, but due to how frustrating the bug and Halo 2’s legendary is we stopped after the last attempt. We can’t find anything online about this bug, I don’t know how many people did Halo 2’s legendary on co’op due to it being the worst of the main series. But, due to this bug we are unable to finish this game together while we did all the others. We do not get a error code, it just disconnects us from the game and puts us on the menu. If anyone can give any info on a fix or any info about the crash would be great. Both of us have computers that can easily handle the game, and internet that is more than fast enough to prevent loss of connection so neither is the issue. As stated above before the last playthrough attempt we had uninstalled and reinstalled the game and had steam run the repair tool, but we still had the crash on the exact same part.

Just encountered this problem and decided to look up if i was alone or not and i found this thread.

I have the same exact issue as you playing MCC halo 2: uprising co-op legendary, we either get kicked back to the menu or we can look at each other but can not move.

How can we get a fix for this? halo reach co-op was another unplayable 1 for us as the lag was very bad no matter what we did, all other halo games did not lag like reach did.

Can confirm, this is still an issue. Playing on Xbox, co-op over live. Two games in a row the mission froze up then kicked us out and broke the party. I have a hypothesis that skipping the cutscene may enable finishing the mission, but after having the issue happen twice in a row, we weren’t keen to try again and just skipped it.

Sometimes Steam can’t detect if the map is corrupted properly. I suggest you two go into your game’s folder, delete the map you’re trying to play (08a_deltacliffs.map) as well as halo2.dll, and then verify your files. I can’t guarantee this will work, but it’s the best shot I’ve had with user who have had a similar issue.
