Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. 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)
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.
