My sister and I were playing online Co-Op Halo CE on MCC a few nights ago when the game paused on my sister’s computer. She was riding in a scorpion tank on the level Assault on the Control Room around the part where you can choose to go around the bend or through the tunnel to get to where you fight a Wraith with two turrets (should probably mention this is on Legendary) when she abruptly couldn’t move anymore. She died by two hunters and responded next to me, but on her screen she was still in the tank with nothing happening. She could look around the tank, but couldn’t move or even exit the tank.
When she did use WASD she would move on my computer, but not her own. When she jumped once, she continued to jump indefinitely from one space press. I don’t think it matters, but just in case it does, we were collecting skulls and terminals as well.
We had to restart the level to get rid of this, but don’t worry, we still beat the game despite this happening on one other occasion accept in a ghost that time. We are wondering if this is due to our internet because I know servers in campaign are P2P, or if it’s something else entirely. Thanks for clicking on this, I hope to find an answer someday.
