Locate the Human Torch icon on top of the Baxter Building in Manhattan; it's the tall white building. He will be there depending on how many races you have acheived medals in.
Easier Combat Tours
The last battle of a Combat Tour is the hardest. If you end the second to the last battle with most of your health, do not pick up the health icon that appears. Go to the last battle and fight. If you are low on health, simply webswing back to the area of the previous fight and the health icon will still be there. Take it and return to complete the last challenge. Also, make sure to spread out the enemies and try to lure some of them to other areas. Some will follow and some will stay behind making it easier to fight them.
No police or military
While playing as Venom in Free Roam mode, destroy something to enter a mini-game where the police and military will try to kill Venom. Then, pause the game and choose the "Unlockables" selection. A message will appear saying you will exit your mission if you continue. Confirm to exit the mission, then exit back out of the "Unlockables" screen and return to the game. Venom can now destory anything without the police or military appearing and attacking him.
Change time of day
While playing as Spider-Man or Venom in Free Roam mode, pause the game and select the "Switch Hero" option. When the next stage loads, it may be a different time of day. Keep switching the hero until it is the time of day desired.
While standing idle and facing an enemy, press Grab(2). Spider-Man will leap over, grab them by the head with his legs and flip them over.
Spider-Man can wall run, but not quite as long as he did in Spider-Man 2. While webswinging towards a wall, tap Grab just before hitting the wall and press the direction you want to run. Note: Do not hold the button. Spider-Man will run for awhile before crawling.
Completing Beetle chase with Spider-Man
Immediately grab the two pedestrians and webswing them to the ambulance one by one. Then swing into the tunnel. Once Beetle puts up the forcefield, climb up the wall and out of the tunnel. Since Beetle sets so many forcefields at varying heights, you need to always webswing while holding R + Webclimb during the chase. This will allow Spider-Man to get the necessary height he needs at all times. Just follow Beetle through the streets, stopping only to save the woman in the burning building and the citizens in the cars.
Defeating Beetle with Spider-Man
Wait on the bottom level of the construction site and eventually Beetle will come to you. When he appears, attack him with punches and kicks and repeat as necessary to defeat him.
Defeating Beetle with Venom
Use the camera lock feature so you will always have Beetle in your sights. Wait for him to zoom close to you and use a tentacle attack on him when he is close to you. When he puts up the forcefield and opens the pits, run to where he is hovering and strike him with a tentacle attack. Make sure to avoid his various projectile attacks by jumping over them.
Defeating Carnage with Venom
Use tentacle attacks to keep Carnage at a distance. If you can get close, use claw attacks which are more powerful. Feed on the policemen on the scene to regain health. When Carnage escapes to the next room, go to the door with the blue circle and press Grab to start a door opening mini-game. Carnage will recharge his health a few times during this fight so continue to feed on the policemen. Watch for Carnage's spinning tentacle attack and jump out of the way.
Defeating Electro with Venom
Smash the neon signs in Times Square by jumping towards them and using a tentacle attack or by throwing cars at them. Smash a few signs and then pick up cars and throw them at Electro. Try to smash as many signs as possible, as Electro uses them to recharge. When Electro goes near Spidey, throw cars at him. Also, bust open the fire hydrants to cause water to shoot out, as the water will harm Electro. Once all of the neon signs are smashed, throw cars at Electro until the battle is over.
Defeating Green Goblin with Spider-Man
Use the camera lock feature. Jump over the Green Goblin's fireballs. Only get in close for an attack when the Green Goblin is no longer on fire. Retreat and repeat the process for both phases of this Boss battle.
Defeating Human Torch in second race
This race is tough because of the varying heights of the spheres Spider-Man has to pass through. Immediately double jump and webzip to the building to the right of the first sphere, then double jump into the sphere to activate the next one. While webswinging, hold R + Webclimb to always climb higher while swinging. This will make the race easier and you won't miss as many targets.
Defeating Rhino in first battle
Jump on his back by pressing Grab, then hit him repeatedly. Jump off just as he starts to fall over. Run over to the wet cement and try to get Rhino to charge at you. When he is stuck in the cement, jump over to the crane and press Grab to use the wrecking ball.
Defeating Rhino in second battle
Dodge his attacks and jump on his back by pressing Grab when his back stops sparking (and turns blue). Hit him repeatedly and jump off when he is about to fall over. Repeat until he goes down.
Defeating Sable with Peter Parker
Move around as much as possible getting in some hits when you can and then retreat to a safe distance. Defeat her henchmen as soon as they arrive so you can focus on her.
Defeating Venom in first battle with Spider-Man
Punch and kick Venom with the 4 combo attack ability (or just punches and kicks), then immediately jump out of the way. Continue this until the fight ends.
Defeating Venom in second battle with Spider-Man
Attack Venom as you have in previous battles. Get close for 4 to 5 hit combos and then retreat. Jump over tentacle attacks and other projectiles like cars.
Defeating Venom in third battle with Spider-Man
Attack Venom from behind when he is at the helicopter. You can usually get in 5 hits safely before he attacks. Once you attack him, use webzip to get as far away as possible. Venom will then jump towards you and either attack or throw objects. Get in quickly and unleash another flurry of combo hits on him. He will then return to the helicopter and you must repeat this process, only later you will have to avoid the fire that spreads on the roof.
Defeating Wolverine with Venom
Use tentacle attacks, throws, and claw attacks against Wolverine. Feed on the bar patrons while Wolverine is stunned to fill up your energy.
