The game has the BEST save system of any first person shooter, ever. There is quick save. "Real" saving where you hit escape and go through the menu and assign a save slot. Check point saves where you just have to pass a brightly-colored cell and it takes care of things for you. When you die you get the option of coming back to one of those cells instantly, or waiting a little while for the game to load your last properly-saved game.
