Go east next and access the tech panel here to activate the scepter. Proceed to the lower level and fix the turnstile switch to the right and then turn both switches. For the last bit, there's a machine at the southwest corner that tells you the sequence in which the pressure plates must be activated. Check the color order then solve the puzzle to proceed.
Now for the level proper, you will start in the lab with Tony Stark and Bruce Banner as your team. As Tony Stark, repair the busted robot somewhere in the room. Smash more stuff in the back to create a S.H.I.E.L.D. terminal then access it to unlock the door.

Go inside and destroy the glass object to uncover a vent Vision cam pass through. Once in the other room, use telekinesis on the table here to rebuild this collectible.
Access the tech panel to power up to robot that Tony Stark fixed previously. Take the robot to the right side of the room and have it access the red handle on the item there. Create a turnstile switch from the bricks that appear. Use that one to uncover a couple of pressure plates. Step on one and grab the card from the cabinet that opens. Use that in the middle of the room and access the new tech panel to find a second card. Go back to the middle of the room and use it there as well.
Minikit #03: There is a destructible air duct above the cabinet to the right of the room.
Minikit #04: During the second part of this level (Party), aim at the target markers behind the bar, construct a speed pad from the bricks and use it.

Minikit #06: Simply inflate a total of three Iron Man balloons to be rewarded with this collectible.

Power up the piano that appears with Thor's lightning Next, go right and check between the boxes where Falcon is chilling with your scanner. to uncover the destructible bits. Then equip Tony Stark with an Iron Man armor (press and hold the character swap button). Smash the crates with help from the armor then construct a pool table.

Minikit #07: Pick up the chair off to the right of the main room using telekinesis. Then grab the minikit by flying or by leaping off the chair.
Minikit #08: Bust up the furniture next to the bar on the right, then use the pieces to construct a vent for Vision to enter. Once you get to the other side, take some with digging capabilities to collect this minikit.
Iron Man MK16 Character Token: Have Cap put out the flames off to the rear of the area to find this token.
Switch to Cap, kill the hostiles and jump down to the lower level to hit the switch located just over Ultron. Construct a trampoline before having Hawkeye shoot at the socket over the trampoline. Use that to swing west afterward. Smash all the destructible objects you find here to create a tech panel. Access it to get the Iron Man armor.
Minikit #09: For this minikit, you have to destroy the speaker off to the west side of the upper section, then use Hawkeye to yank at the handle inside.
