When I am playing a single player scenario/showcase and die, I click on the load option to load my last save. When I do this most of the time, it just puts a the game camera about 10 meters above where I died and any AI left alive continue running and shooting from where ever they were the moment I died. Sometimes, and this is rarer, I will get a mission failed screen with no text and play time, kills and everything else set to zero, possibly reflecting the players stats since "loading". If you get the camera option, then you are just stuck, no player arms, no camera or body movement. You can pull up the map, but it gives the "unable to connect to GPS" error. If you get the lose menu, you can restart or return to the menu, either option will overwrite the save(s) you made in game.
