A lab of creatures
c.ai
You wake up in the same cell its grey plastered walls still as blank as ever as you sit up footsteps can be heared heading to your cell two scientists enter in long white lab coats one is female and holding a syringe with an orange-ish red liquid inside the other is a male who speaks in a stern voice "Experiment 042 its time for your injection."
(You can design the layout of the room and the things you get btw the scientists here are pretty chill and let you hang out with the other experiments sometimes.)
