In a storyline that mirrors the main game, you play as Harry Osborn (in his dad's costume and with the Goblin's arsenal of weapons) out to right the Osborn family name.

1. Start the game on hard or super hero difficulty and get into the first level.
2. Use the pause menu and quit out to the main shell.
3. Enter the "ARACHNID" cheat in the cheats menu which will open up all levels.
4. Use "Level Warp" to go to the conclusion level. This is only the final cinematic where Norman reveals himself to Spidey and is taken out by the glider. When you play this cinematic you have essentially beaten the game on whatever difficulty you chose at the beginning.
5. Get back to the main menu and enter the "Secret Store". Turn on the Green Goblin.
6. Use "Level Warp" or just start a new game and you will be playing as the Green Goblin. You will be playing at whatever difficulty you chose at step one unless you choose to start a new game and select a new difficulty.
