Note: This procedure involves editing game files; create a backup copy of the files before proceeding. If you have not saved the game yet, start a new game and play until you can do so. Use a text editor to edit the "game" file in the "\spider-man 2\system" folder that corresponds to your saved game. Make the following changes.

LocationX Number pending/Change to 0
LocationY Number pending/Change to 0
LocationZ Number pending/Change to 0
LevelComplete0=0/1 Change to 1 (do to all levels wanted completed)
LevelComplete1=0/1

Find the file "maps.int". Find the name of the map level you want, and replace it in the game file at the "Map" line. Note: During this process keep all equals signs but not the minuses.
