Challenge 1: Finish Line
To complete this challenge, simply finish the level.
When the level starts, follow the walkway and clear out the enemies just around the corner. As you do, make sure you stay away from any explosive barrels that are triggered during the fight.
Destroy the terminal located just past the first group of enemies to drop the lift down to your position. Search the area for studs and breakable objects, then use the lift to ride up to the next walkway.
When the lift stops, clear the enemies from the walkway and dash away from the exploding barrel that drops into the area. When you’re ready, move toward the bottom of the screen and assemble the Build-it at the end of the lift. When the lever is in place, use it to activate the nearby gears.
Climb onto the nearest gear and ride up to the next floor. Make sure you hop off before you get crushed in the mechanism. If you like, search the platform near the top of the screen to find some enemies, studs, and breakable items. Otherwise, move straight to the platform near the bottom of the screen to progress through the level. Deal with the waiting enemy, then follow the ramp down to the next area.
As you deal with the enemies along the main path, pay attention to the red valve handles and explosive barrels located among the large pipes. Destroying these objects can result in devastating chain reactions. You can use this to your advantage, but make sure that you don’t get caught in accidental blasts.
Clear out all the Hydra goons as you continue along the main path. Dodge incoming projectiles, and keep your distance from any explosive barrels. Be particularly careful when you deal with the enemies on the small lift—it drops through the floor when the nearby control box is damaged.
As you approach the far end of the map, a cinematic shows a Hydra heavy goon lift a container above his head. When you see this, prepare for the impending attack. Either move toward the top of the screen to avoid the container when it comes bouncing down the path, or stand your ground and shoot the container to send it flying back into the heavy goon.
Clear out any remaining enemies, then locate the forklift near the end of the map. Use the nearby Build-it to repair the forklift and send it crashing into the nearby hatch. When you’re ready, head through the open hatch to finish the level.
Challenge 2: Stud Collector
To complete this challenge, you must collect over 50,000 studs before the level ends.
This map contains loads of studs and breakable objects, but it can still be difficult to meet the stud requirement without making a little extra effort. Look for the destructible wall panels scattered throughout the level to find a few valuable stud stashes.
If you’re unable to find the required studs during Story mode, complete the challenge during Free Play. Use Spider-Man to collect the purple stud at the end of the climbing wall.
Challenge 3: Minikit
To complete this challenge, you must collect the minikit hidden in the level.
Follow the main path until you reach the bottom of the ramp, then locate the destructible wall panels along the back wall.
Smash the panels to reveal a stash of studs and this level’s minikit.
Challenge 4: Heavy Metal
To complete this challenge, you must defeat the Hydra heavy goon within the 90-second time limit.
The simplest way to beat the clock is to race along the main path and counter the heavy goon’s initial attack. However, as long as you move quickly, you should have plenty of time to defeat the Hydra heavy goon using any tactics you like.
Challenge 5: Civilian Peril
To complete this challenge, you must rescue two civilians before you complete the level.
Both civilians are in the cell near the bottom of the ramp. After you unlock Jean Grey, revisit this level during Free Play. Follow the main path until you reach the bottom of the ramp, then defeat the Hydra goon near the wall to the right. When it’s safe, use Jean Grey’s telekinesis to move the bars and rescue both of the civilians.
Challenge 6: Clean Sweep
To complete this challenge, you must defeat all 25 of the Hydra goons scattered throughout the level.
Most of the enemies are located along the main path, but there are a few Hydra goons you may miss if you rush through the level. When you ride the lift near the starting location, move toward the top of the screen and make sure that you deal with the goons that leap out of the large hatch. Attack them directly, or destroy the nearby terminal to bring the hatch crashing down onto them.
After you ride the large gear, search the platform near the top of the screen to find two more hidden enemies. Make sure you deal with them before you return to the main path.
The remaining Hydra goons are scattered along the main path. Make a thorough sweep of each area to ensure that you clear out all available enemies on your way through the level. You should have defeated 23 enemies by the time you reach the end of the map. You automatically defeat the last two enemies when you send the forklift smashing through the exit.
Challenge 7: Combo Master
To complete this challenge, you must perform a ×10 combo.
Black Widow’s ranged attack is great for building huge combos. Find any cluster of two or more Hydra goons and fire a steady stream of ranged attacks to earn your combo. As you do, alternate your attacks between each enemy to prevent them from charging their weapons.
Challenge 8: KABOOM!
To complete this challenge, you must defeat the Hydra heavy goon by hitting him with the container he throws at you.
When the Hydra heavy goon throws the container, use ranged attacks to blast the container back to him. Stand on the metal grating to ensure that you’re in the proper position, then fire a steady stream of ranged attacks until the container bounces into range. Shoot the container before it reaches you to send it flying back to the Hydra heavy goon.
Challenge 9: Going Pro
To complete this challenge, you must finish the level without using a Super Move.
Black Widow’s rapid-fire ranged attacks are more than a match for any number of Hydra Goons. Simply refrain from using Super Moves to complete this challenge.
Challenge 10: Multi-Challenge
To complete this challenge, you must not only avoid taking damage for the duration of the level, you must also use a civilian to finish the level within the 100-second time limit.
After you unlock Free Play for this level, use any available civilian character to revisit the map. To stay ahead of the clock, it’s best to avoid all unnecessary combat. Keep your distance from explosive barrels to stay healthy as you race through the level.
You’re free to switch to Black Widow as you progress through the level—just make sure that you’re playing as your civilian character when you finish the level.
