The Thing Simulation

Ever since I learned how to use raycasts in Unity, I've had the idea to make a simulation, specifically about The Thing. This whole thing (haha get it?) is basically just somewhat of a virus simulation. You have 4 'humans' running around a little base, a shapeshifting threat makes its way inside, what happens then?

This is probably the coolest thing (okay this time the pun wasn't intended) I've ever made in Unity. The AI for the humans is made up of exactly 389 lines of C# code, and I somehow managed to write most of it all in one day—I thought this was going to be project I would spend like a week on.

Also, for the 'Paranoia Level' in the simulation menu, you have to restart the simulation for your changes to apply.
