It's kind of like what the first Halo pushed, technically speaking, when it would be loading up the next part of a level in those long hallways and all you'd see is a small word in the corner for a second.

I'm just wondering how they handle saves/checkpoints/pause menu's when going for something like this. No matter how well done and immersive this is and how much some people will want to sit through it possibly, it's still going to have to fit that aspect of playing of game in there somehow.
