At the end of my gaming session last night, I went to try and save and realized that there didn't appear to be an option. I'm assuming the game's autosave is all I get, like it or not.
If I quit the game during a mission, will I start back up at the last checkpoint I passed, or do I have to start the mission over from the beginning? Sometimes the missions chain into each other (or I don't realize I've started a new one) so I frequently don't have time to finish what I started.
