Origin of the Start of the Rise of the Plant of the Apes
Found next to the Genetics room, naturally, the Monkey Dome is the most constant, reliable source of test subjects that won't grow bored... just handle them with care. Three monkeys already live here, and there's several more in the ValuChimp kept in here by who-knows-what. There's also two lockers each with blindfolds and electropacks for discipline, so you don't get wiped out by rampaging simians two minutes into the shift.
For some info about the genetics research these monkeys are used for, check out the Guide to Genetics.
There is no vent. The monkeys could not afford one.
The APC is on the north wall of the room.
