So, after five hours of playing Reach on Legendary today, the power cut and wiped everything I have done. Anyone else suffered from a lack of autosave? Isn't this such a basic thing that it should be in the game from the get-go? I was loving everything about the game ad was halfway through mission five when everything died. Now I'm all the way back at the start of night fall. I need a break now and it's a shame because I really wanted to see what this story was going to do but I've just lost my momentum.

Every checkpoint and end of level is a save point, you probably get something like 5/6 saves in just one level. 
 
Hang on, you're complaining about 1 level's worth of loss? That did not take you five hours surely!?

Dude. It's a Halo game with checkpoints. Checkpoints have been in Halo since 2001, the first game.

I've never lost more than 5minutes of playing at a time.

I lost 30 - 45 mins once because some stupid AI bitch wouldn't follow me.

My internet cut out and after attempting to sign back in (and failing) it signed out my profile. I lost over two completed missions of legendary play. WHAT THE FUCK BUNGIE

I am completing levels one at a time, and I have not had trouble losing data. At the VERY least doesn't it check off that level as completed on Legendary once you are done with it? Sure, you have to Save and Exit in order to resume mid-level, but you should never lose more than that. So that's like, what, 45 minutes to an hour or so on Legendary? That's about what I was running on some missions. Don't get me wrong, I'd be pissed if I lost an hour of progress in a level on Legendary, but I just hope you guys aren't playing levels again that you don't have to. Especially if you are doing the Solo Legendary Run.
