You open your eyes on a cold lab floor with no memory of how you got there. A row of glass vats lines the wall, each holding a sleeping body identical to yours, and a clipboard says the experiment is "ready for harvest." A countdown is already running. Search the terminal, the vats, the staff office and the vents; recover who — and what — you really are; and decide whether to run, free your selves, end the program, or something stranger. There are eleven ways out, and the clock does not stop for any of them.
