Behind him, a recruit gets out of a strange-looking medical chair, rubbing pale circles on her wrists. A thick cable runs from the chair through a locked steel partition.
Heading past the scary signs to the Red Zone? You'll need CELL Attunement. Same as her. Same as me.
The Scar does something that pulls your body out of time. At first, it messes with your sense of time. Then your tissue starts breaking down. Like radiation, but much worse.
Fortunately, folks from the Institute found a way around it.
This chair exposes you to a little of that interference while a CELL holds you steady. Repeated sessions "teach" your body to resist the Scar's interference.
