After completing the Final Showdown mission, Go on the map and look for the Financial District. Go there and head to the left until you see a glass building. This is the construction site after it was broken Note: You can see the little square that you was fighting in with Venom and Sandman.
In your last fight with Shriek, she temporarily takes away your Black suit and uses people from your imagination attack you. Wait until the Black suit recharges to switch over and detect your true enemies. Keep attacking Shriek until she changes you back to the old Spider-Man. Repeat these steps until she collapses.
As Black costume Spider-Man, find the meteorite fragments (small rock objects surrounded by a purple/pink glow) by listening for a pulsating sound. The louder it gets, the closer you are to the fragment.
Once you defeat The Sandman for the first time during the “Mary Jane's Favorite Band" mission and before you "Meet Mary Jane At The Restaurant", you cannot remove the Black suit. During this time, which lasts until you start the next mission, you can wear the Black suit without any damage being done to you. Use this time to clear the city of all gang activity. This takes a long time but is easier with the Black suit.
While web swinging, press Z for the boost and hold it. When you reach the end of your swing, press C and rotate the Nunchuk to the LEFT or RIGHT, while still holding Z + C. Spider-Man will then look like he is having a spasm and remain at the end of his swing, defying the laws of gravity. Play around with the Z + C combination to do different things, like a ceiling fan while under the monorail.
-During your first encounter with Sandman, do not try to attack him. Instead, just try to stay close to him. Counter-attack him several times on various levels to finally battle him. You need the Black suit to damage him. Keep hitting him until you are prompted to give him a bath. Repeat until you defeat him.
-The second battle with Sandman is simple. Just dodge when your Spidey senses alert you and run to the yellow circles that appear. Complete the prompts to throw TNT barrels at Sandman. Harry will eventually kill him.
Go to the clock tower in Columbia and get on one of the four sides. Wall crawl up until you get to the clock. Keep wall jumping up until you fall inside. If you are in the black suit you will make a crack. You won’t be able to move unless you web swing, then you’ll will reappear. Note: This doesn’t work all of the time.
Wait until Michael is getting ready to rush you, then open the window. He will be temporarily weakened so attack him. Shriek will heal him at the cost of her health. Repeat this until he dies and she flees.
To easily gain Hero points, take all bosses pictures except one and complete Story mode. Then, take the remaining boss picture to gain 15 Hero points. Save the game, reset the sytem, and load the saved game to gain 15 Hero points. Repeat as desired.
-Before fighting Venom, go to the upgrade menu and make sure you have the melee attack volley. Depending on your health level, you may or may not want to use the power up. At the right moment, jump over Venom, confuse him, and chip away at his health. Repeat until his black suit begins to "glow". Now, when you jump over him he will run away. Take this opportunity to use your new attack and chip at him, occasionally giving some hits. Keep hitting him until his "glow" gets stronger. Harry will eventually tell you to knock Venom into the air. He'll fall back to the ground confused, same as before. Repeat until his health is low and you can finish him off.
-Use the following strategy to easily defeat Venom the first and second time you face. When you meet Venom at the construction site, you must beat him down in five minutes or else Mary Jane will die. The best way to do this is by defeating Venom in version one. Version two is slightly harder. Simply watch his five punch combo and the last punch, which is his super punch. After he is done with his combo, beat him up. Repeat until Venom turns into version three. Watch carefully and you should see a flashing symbol. Once you do, follow what the game instructs you to do and you should win.
-The easiest way to defeat the second Venom is to jump around and fire adrenaline web. When his glow is high, go to the circle and press the selected button.
When you go to a crime area controlled by the police, you will be given a task involving a random gang. When these tasks are completed, the effectiveness of the police will increase as seen by the rings around the police symbol on the map. The more rings you have, the less likely it is for gangs to take control of police-controlled areas and the more likely it is for the police to take over gang controlled areas.
When trying to open the boarded windows, he will do a long jump towards you if you are far away from him, which takes a few seconds to recover from. Don’t stand in the yellow circles before he jumps. Instead, stand next to the wall opposite the windows. He will now jump to there and while he is recovering, pull down the boards. When he jumps into the light, attack him. Keep doing this until him and his wife are defeated. Note: When he flies around, use the Spider-Wall to damage him and he will land
