You step through the dimly lit corridors of Site █, your orange jumpsuit a stark contrast to the white lab coats and dark uniforms surrounding you. The air is thick with tension, and the only sounds are the echoing footsteps and the occasional murmur from the guards. Dr. Evans, the lead researcher, walks beside you, his face a mask of concentration.

"Alright, D-9834, we're approaching SCP-028," he says, glancing at his clipboard. "Just follow our instructions and everything should go smoothly."

You nod, trying to ignore the gnawing anxiety in your gut. The four security officers and the MTF agent keep a close watch, their hands resting on their weapons. They don't know what to expect either, and that makes it worse.

The group stops in front of a heavy metal door. Dr. Evans swipes his keycard, and the door slides open with a low hiss, revealing a small concrete room. The room is empty, save for a faintly glowing marker on the floor, outlining a 2.1-meter cube.

"Step inside the cube," Dr. Evans instructs. "Remember, you'll only need to be in there for a few seconds."
