Deus Ex Wiki says about the Wan Chai Market level:
If the player noclips into the scenery above the police station, they may find a Red Arrow thug stuck in a T-Pose. If removed from the T-Pose, he will speak to the player in dialogue cut from the final game.
I could find a closed and unused room above the police station, but that room is totally empty. It has only some pillars with their shadow, but nothing that I can use. How can I make the mentioned guy appear?
