Follow the trail of ghost studs to the Watchtower’s containment cells, where you recently battled The Joker and Lex Luthor. Use Batman’s Electricity Suit to safely approach the central EMP device, then destroy it to expose a portal for Martian Manhunter (or Miss Martian).
Move Martian Manhunter onto the portal and press the Interact button. He travels through the floor and emerges on a higher ledge, beyond the room’s outer forcefield. Only Martian Manhunter (or Miss Martian) can travel through portals like this!
Press the Interact button and use Martian Manhunter’s mind control on the worker in the next room. Direct the worker to pull the room’s lever, and you deactivate the room’s forcefield, letting the rest of your friends join you.
Circle around the walkway and use either Cyborg’s Demolition Suit or Batman’s Power Suit to destroy the silver debris that’s blocking the gold background wall. Use any character’s laser or heat vision afterward to cut a bat symbol out of the gold wall, then proceed through the opening to advance to the next mission.
