Vault 110: Would be populated by 17 average people and one human hunting killer. It would be made to look like a square forest (1 sq mile) with cameras placed in the ceiling at even intervals and in some of the trees. The average people are released into the vault at 17 different places, and the hunter enters the day after. The people each have a 9mm pistol with one clip and the hunter has a knife. A stream runs through the center of the forest, and animals are released into the vault before human inhabitants are. The experiment will be to see if the hunter can take down all the humans or if they can kill him (not the best of experiments, but it sounds worthwhile to me).
Note: The hunter knows that the people have pistols, but the people only know that the other 16 are in the vault
