After 36 hours progress on Just Cause 2 - I got stuck, so I started a new game. It warned that this would overwrite autosave data but I went ahead and started a new game - does this mean I have totally lost the old game - all that 36 hours progress? Is there any way to bring that old game back - I mean surely the PS3 saves a certain amount of the progress somewhere? Please help!
Did the auto save function kick in during the "new game"? If so I'm afraid its lost.
The way saved games are handled in Just Cause 2 is that you are expected to save regularly to ensure progress isn't lost. The auto save only takes up one "slot" and is rewritten frequently.
It's actually more of a safety net against random deaths or errors than a long term way to save your game.
You should always save your game manually trough the menu, so whenever you start a new game and your auto-save file is overwritten, you will be able to load it back up using one of your 10(or so) custom save slots.
For those on the pc: The save files are located in your documents folder under the name 'square enix/just cause 2/', you might get previous versions back from there if windows automatically saves recent states of that folder.
Good luck re-doing stuff.
though 36 hours isn't much time lost relatively speaking, it took me about 60 hours of gameplay to finish ALL locations AND challenges.
