Last night, I played H2A online coop with the same friend that I played the original game with back in the day side by side. It felt GOOD. Like really good (at least, once I switched my control scheme to Universal Reclaimer and stopped turning my flashlight on when I wanted to reload).

So anyway, we played H2A on Legendary and blasted through Cairo station. It was awesome. Then we got to Outskirts and started out great. We got through the initial firefight with only two small hiccups of lag (where his position would jump a few meters but then he'd be right back on track).

Suddenly, after we took down the hunters and entered sniper alley, I saw his character lag again... and then started running the opposite direction (back towards the level start). His voice in my ear was telling me about the jackal snipers that he was fighting. It didn't make sense.

We quickly realized that we were no longer playing in the same game. He could see my Master Chief, and I his. But the other player was always "backwards"--movement and weapons equipped/firing/reload were preserved but the direciton of movement was always reversed. So the other character in each of our games was usually up against a wall. If one of us died, the other player's game would not reset to the checkpoint, but if we killed the "ghost" avatar in our own game, it would reset as expected. Our campaign score was also still linked. When HE died in his game, I'd continue playing but I'd see the -100 score pop up on my screen. So after 30 minutes or so of trying to "force" the game to resync us we decided to just soldier on and try to complete the level solo and see what would happen.

Sure enough, about an hour or two later, I was able to finally exit the tunnel system and trigger the post game carnage report (was there supposed to be a cutscene? I don't remember). When that happened, his PGCR popped up on his screen, even though in the background his character was still there in the open getting repeatedly pummeled by jackal snipers (and then respawning in the same spot to be killed again).

All-in-all we finished with an impressive -10,000+ score between us. The kill totals on our PGCRs were also way, way off and neither matched. It was just a totally bizarre and unreal experience. When the next level (Metropolis) started, we were back in sync and nothing was wrong..

I wish there was a way to pull up Campaign stats on Waypoint, but I guess that's not a feature for MCC? Oh well...

So has anyone else seen this yet or ever before?
