I have been very frustrated playing the Halo 4 campaign where there is no indication if you have reached a rally point and often rally points are scarce.
For example, I palyed the level called "Reclaimer" and got the to video talking to the Librarian and then ended my game after warping back to the Infinity. It even showed me some text (a chapter title it seemed) after the warp and then I was shocked to find out that the last rally point was back when I left the Mammoth.
There has to be a better way. Probably the DMC method of showing you time since last rally point when you pause, or putting them more often. It is really confusing to watch a long cutscene and then not have the game saved right afterward, so this has to be communicated better.
